5x - 6y = -11
3x + 6y = 3
Answers
First is by substitutingwe would need to free one of the variable to solve it. It can be one or the other it would result in both ways.
5x - 6y = -113x + 6y = 3
3x + 6y = 3
x=(-6y+3)/3
x= -2y+1
Now we use this and put it in the other of the equations
5(-2y+1) - 6y = -11-10y+5-6y=-11
-16y=-11-5
-16y=-16
y=-16/-16
y=1
Now we use this to find x.
x=-2y+1
x=-2(1)+1
x= -2+1
x=-1
Now that we now our variables we have to check if the are correct.
5x - 6y = -115(-1)-6(1)= -11
-5-6=-11
-11=-11
3x + 6y = 3
3(-1)+6(1)= 3
-3+6=3
3=3
So yeah x=-1 and y= 1
That's a way to solve it there is another way that is by eliminating.
so i this we have to delete a variable in both equations. In thi scase we can take y becuase if we sum the bothe quation 6y and-6y get eliminated.
5x - 6y = -113x + 6y = 3
8x= -8
x= -8/8
x=-1
Now we use this to find the other variable
5(-1) - 6y = -11-5-6y=-11
-6y= -11+5
-6y=-6
y=-6/-6
y= 1
So now we have to check if the are correct.
5x - 6y = -115(-1)-6(1)= -11
-5-6=-11
-11=-11
3x + 6y = 3
3(-1)+6(1)= 3
-3+6=3
3=3
That's that
X= -1
Y= 1
Hope it helped
3x + 6y = 3
Rearrange the 2nd equation:
3x + 6y = 3
Subtract 6y to both sides:
3x = -6y + 3
Divide 3 to both sides:
x = -2y + 1
Plug in 2y + 1 for 'x' in the 1st equation:
5x - 6y = -11
5(-2y + 1) - 6y = -11
Distribute 5:
-10y + 5 - 6y = -11
Combine like terms:
-16y + 5 = -11
Subtract 5 to both sides:
-16y = -16
Divide -16 to both sides:
y = 1
Plug this into any of the two equations to find 'x':
3x + 6y = 3
3x + 6(1) = 3
3x + 6 = 3
Subtract 6 to both sides:
3x = -3
Divide 3 to both sides:
x = -1
So our solution is:
(-1, 1)

x<-5
If I read the question correctly and x stands for a variable, and not multiplication, you can multiply each value by 10 to get whole numbers (or not, but whole numbers are easier to work with, and you get the same answer either way, I checked). This gives you
-4x -12>8
First you want to isolate x by adding 12 to both sides and getting. -4x>20. Then you divide both sides by -4, but when doing so, remember that when you divide by a negative number, you need to flip the sign. So then your answer is x<-5.

What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ 1/8 = m/32
Now,
Solve the equation for m as;
The expression is,
⇒ 1/8 = m/32
Multiply by 32 both side, we get;
The expression is,
⇒ 32/8 = 32m/32
⇒ 4 = m
⇒ m = 4
Thus, The solution of the equation 1/8 = m/32 will be;
⇒ m = 4
