Question

Solve the following equation by combining like terms: x +x +2 +3x- 6 = 31

Answer 1

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
