Question

Solve the linear equation x + 3 + x - 8 + x = 55 State the property that justifies your first step and why you chose it.

Answer 1

X=20
Subtract the numbers: x+3+x-8+x=55 -> x-5+x+x=55
Combine like terms: x-5+x+x=55 -> 3x-5=55
Add both sides: 3x-5+5=55+5 -> 3x=60
Divide: 60/3 = x=20

Answer 2

Answer: X=20

Explanation:

Subtract the numbers

combine like terms

add both sides by 5

simplify

divide both sides by the same factor

Simplify

and bam you got 20
