Solve using the substitution method Y+2x=7
14-4x=2y
A the solution is (1,5)
B the solution is (21,0)
C there an infinite number of solutions
D there is no solution
Answers
Since the value on both sides are the same, hence there are infinite number of solution for the system of equation
System of equations
Given the system of equations expressed as:
Y+2x=7
14-4x=2y
Using the substitution method.
From equation 1, y = 7 - 2x
Substitute into equation 2
14-4x = 2(7 - 2x)
Expand
14 - 4x = 14 - 4x
0x = 0
Since the value on both sides are the same, hence there are infinite number of solution for the system of equation

7-2x=y you will need this on the next step
-----------------------------------------------------
y+2x=7
y=7-2x
(7-2x)+2x=7 -------> 7-2x+2x=7
7=7
The answer is C.

Answer:
The slope is and the y-intercept is
.
Explanation:
This function is written in slope-intercept form, which is . In this form,
is the slope and
is the y-intercept.
In this case, and
, so those are the answers to this problem.
For this case we have that by definition, the equation of a line of the slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cutoff point with the y axis
We have the following equation:
So we have to:

x = variable
3x = term
5 = constant
3x + 5 = expression
3x + 5 = 20 = equation.
3x + 5 = 20
A coefficient is the number before any variable. So 3 is the coefficient.
A variable is a letter which stands for a number. So x is the variable
A term is a coefficient and variable together. So 3x is the term.
A constant is a number on its own. So 5 is the constant.
A expression is a mathematical phrase. So, 3x + 5 is the expression.
A equation is a way to show that 2 things are equal in math. So 3x + 5 = 20 is the equation.
So,
Coefficient = 3
Variable = x
Term = 3x
Constant = 5
Expression = 3x + 5
Equation = 3x + 5 = 20

+ y = -1 ⇒ y =
- 1
To graph this line, plot a point at the y-intercept (0, -1), than plot the next point using the rise over run from the slope by counting up 1 and to the right 3 of the y-intercept. This gives you a second point of (3. 0). Draw a line through those two coordinates.
Answer: Plot (0, -1) and (3, 0) and draw a line through them.

y = 4 + ⇒ y =
+ 4
Same as above. Plot the y-intercept (0, 4) and then use rise over run from the slope to plot (3, 5).
Answer: Plot (0, 4) and (3, 5) and draw a line through them.
