Answer:
Step-by-step explanation:
Simplifying
(15x + -2) + (7x + 4) = 90
Reorder the terms:
(-2 + 15x) + (7x + 4) = 90
Remove parenthesis around (-2 + 15x)
-2 + 15x + (7x + 4) = 90
Reorder the terms:
-2 + 15x + (4 + 7x) = 90
Remove parenthesis around (4 + 7x)
-2 + 15x + 4 + 7x = 90
Reorder the terms:
-2 + 4 + 15x + 7x = 90
Combine like terms: -2 + 4 = 2
2 + 15x + 7x = 90
Combine like terms: 15x + 7x = 22x
2 + 22x = 90
Solving
2 + 22x = 90
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2' to each side of the equation.
2 + -2 + 22x = 90 + -2
Combine like terms: 2 + -2 = 0
0 + 22x = 90 + -2
22x = 90 + -2
Combine like terms: 90 + -2 = 88
22x = 88
Divide each side by '22'.
x = 4
Simplifying
x = 4

Answer:
![y=-\frac{1}{7}x+9](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B1%7D%7B7%7Dx%2B9)
Step-by-step explanation:
The slope-intercept formula is:
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
y= keep as variable
m= slope of the line
x= keep as variable
b= y-intercept of the line.
