Question

solve the simple equation 3(x+1)=12+4(x-1)​

Answer 1

Answer:3(x+1)=12+4(x−1)

Use the distributive property to multiply 3 by x+1.

3x+3=12+4(x−1)

Use the distributive property to multiply 4 by x−1.

3x+3=12+4x−4

Subtract 4 from 12 to get 8.

3x+3=8+4x

Subtract 4x from both sides.

3x+3−4x=8

Combine 3x and −4x to get −x.

−x+3=8

Subtract 3 from both sides.

−x=8−3

Subtract 3 from 8 to get 5.

−x=5

Multiply both sides by −1.

x=−5
