Answer:
y =
x + 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
- 7x + 2y = 8 ( add 7x to both sides )
2y = 7x + 8 ( divide all 3 terms by 2 )
y =
x + 4 ← in slope- intercept form
3b=$9
let b be comic books
divide both side by 3 which gets you the answer of b=$3
The first equation must be multiplied by 18 and second equation must be multiplied by 8
<em><u>Solution:</u></em>
<em><u>Given system of equations are:</u></em>
--------- eqn 1
-------------- eqn 2
Multiply the second equation by 8 both sides to remove the fraction in the variable y

Multiply the first equation by 18 both sides to obtain the coefficient -3 in the variable y

Add eqn 3 and eqn 4

Thus the y-term is eliminated
Therefore, first equation must be multiplied by 18 and second equation must be multiplied by 8
