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:

$x=0$
