Answer:
x=0
Step-by-step explanation:
10(x-2)=-20
10x-20=-20
add 20 on both sides.
10x=0
10 times 0 =0
10(x - 2) = -20 <em>divide both sides by 10</em>
x - 2 = -2 <em>add 2 to both sides</em>
othrer method
10(x - 2) = -20 <em>use distributive property a(b - c) = ab - ac</em>
10x - (10)(2) = -20
10x - 20 = -20 <em>add 20 to both sides</em>
10x = 0 <em>divide both sides by 10</em>
