Solve:
7y - 8 = 6y + 1 With a detailed step by step solution please! :)
Answers
Combine like terms...
7y - 8 = 6y + 1
-6y -6y
y - 8 = 1
+ 8 + 8
y = 9
Answer: y = 9
7y-8=6y+1
-6y -6y
We subtract because we need it to zero out on the right.
7y-6y-8=1
Now move the -8 to the right by adding it to both sides.
7y-6y-8=1
+8 +8
7y-6y=1+8
remember we added 8 so that this number zeroed out on the left.
Now finish the math
7y-6y=1y or just y
1+8 =9
y=9

48=30+6y
48=6y+30
Flip the equation.
6y+30=48
Subtract 30 from both sides.
6y+30−30=48−30
6y=18
Divide both sides by 6.
6y / 6 = 18/ 6

The problem that could represent the equation is Mariana uses 6 boxes of fertilizer each box weighs 15 ounces How much fertilizer does she use in all
Given that,
- The equation is 6x = 15.
Based on the above information, the information is as follows:
- Here Mariana should used 6 boxes for fertilizer
- And each box should weight 15 ounces.
- So overall how much fertilizer should be used.

Option D: is the point of intersection of the two lines.
Explanation:
The two equations are and
We need to find the point of intersection of the two lines.
Thus, let us solve the equation by substitution method.
From the equation , we shall determine the value of y, by adding both sides of the equation by 6x.
Hence, we have,
Now, substituting in the equation
, we get,
Substituting in the equation
, we get,
Thus, the point of intersection of the two lines is
Therefore, Option D is the correct answer.

For the first one, you would have to subtract 5 from 8 which would give you x=3!! that is your answer. For the second one, you would have to subtract 3 from -6 which would give you -a=-9, but were not done here yet, we are going to multiply this by -1 because you can't have a negative variable which will give you a=9. And last but not least, on the third one, you would have to subtract 21 from 30 which will give you c=9. There is no specific formula to do these problems other than to get rid of the "third wheel number".

The top and bottom faces are 3 inches by 3 inches.
Area = 3 in. * 3 in. * 2 = 18 in.^2
The front, back, right, and left faces are 3 in. by 6 in.
Area = 3 in. * 6 in. * 4 = 72 in.^2
Total surface area = 18 in.^2 + 72 in.^2 = 90 in.^2

y = x - 4
2 * x + y = 5
_____________
2 * x + (x - 4) = 5
2 * x + x = 5 + 4
3 * x = 9 /3
x = 9 / 3
x = 3
y = x - 4 = 3 - 4 = -1
The correct result would be x = 3 and y = -1.
-x + y = -4
2x + y = 5
-(2)x + (2)y = (2)5
(x cancels) 3y = 15
y = 5
plug y into one of the two original equations to solve for x:
5 = x - 4
x = 9
The answer is x = 9, y = 5, or (9, 5)
