Answer:
x=7
Step-by-step explanation:
We want to get the variable "x" alone to get our answer. So.
1. combine like terms
x+x+2+3x-6=31
like terms in equation: (left side)
x, x, 3x= 5x (equation: x+x+3x)
2, -6= -4 (equation: 2-6)
so, this is what the equation would look like with our new answers:
5x-4=31
2. add 4 to both sides
5x-4+4=31+4
(on left side of equation, the -4 and +4 cancel each other out, leaving the 5x alone)
5x=35
3. divide 5 from both sides, to get the "x" alone
5x/5=35/5
so, our answer would be:
x=7
