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
