Question

3(1+x)=2[3(x+2)-(x+1)]

Answer 1

3 + 3x = 2(3x + 6 - x - 1)
3 + 3x = 2(2x + 5)
3 + 3x = 4x + 10
x = -7

Answer 2

Answer:

x=-7

Step-by-step explanation:

3(x+1)=2[3(x+2)-(x-1)]

distribute the 3 and the - inside the brackets

3(x+1)=2[3x+6-x-1]

now distribute the three inside the parenthesis and the 2 inside the brackets

3x+3=6x+12-2x-2

combine like terms

3x+3=4x+10

subtract three from both sides and subtract 4x from both sides

-x=7

divide whole equation by -1

-x/-1=7/-1

simplify

x=-7
