Question

What is the value of x in the equation 2(x – 3) + 9 = 3(x + 1) + x?
x = 
​

Answer 1

Start with

`2(x-3)+9=3(x+1)+x`

Expand both parentheses by multiplying both terms by the number outside:

`2x-6+9 = 3x+3+x`

Sum like terms:

`2x+3 = 4x+3`

Simplify the "+3" on both sides:

`2x = 4x`

Subtract 2x from both sides:

`2x=0`

Divide both sides by 2:

`x=0`
