<span><span>If you would like to solve the equation </span>- 7 * x - 3 * x + 2 = 8 * x - 8, you can calculate this using the following steps:<span>

- 7 * x - 3 * x + 2 = 8 * x - 8
- 7 * x - 3 * x - 8 * x = - 8 - 2
- 18 * x = - 10    /(-18)
x = 10 / 18
x = 5/9

Combine like terms. 

-7x - 3x = -10x
-10x + 2 = 8x - 8
+10x        +10x

2 = 18x - 8
+8          +8

10 = 18x

18x/18 = 10/18
x = 5/9

What is the slope-intercept equation of the line shown below? (3,4) (-3,-2)
AysviL [449]
Find the gradient
m = y2-y1 / x2-x1
m = 4-(-2) / 3-(-3)
m = 6 / 6
m = 1

Insert the values of one of the points into y=mx+c to find c (choosing point (3,4)):
y = mx + c
4 = 1(3) + c
c = 4 - 3
c = 1

Therefore, the equation is:
y = x + 1
