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
