Answer:

x=4

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

7x−2(x−10)=40

7x+(−2)(x)+(−2)(−10)=40(Distribute)

7x+−2x+20=40

(7x+−2x)+(20)=40(Combine Like Terms)

5x+20=40

5x+20=40

Step 2: Subtract 20 from both sides.

5x+20−20=40−20

5x=20

Step 3: Divide both sides by 5.

5 divided by 20 = 4

5 divided by 5 =1

x=4

What is an equation of the line through (0,-3) with slope 2\5
baherus [9]
M=2/5  , (0,3)
use y= mx+c ,   find c first.
-3 = (2/5) 0 + c
c = -3
Thus the equation will be y=(2/5)x - 3.
or in some case,
(y1-y)=m(x1-x)
(-3-y)=(2/5)(0-x)
