Question

Solve the linear equation x+4+3x=72 state the property that justifies your first step and why you chose it.

Answer 1

Answer:

Step-by-step explanation:

problem          justification

x+4+3x=72         given

4x+4=72            combine like terms or simplify

4x=68                subtraction property

x=17                  division property

Answer 2

Equation: X+4+3x=72

This can be simplified to 4x+4=72
Move the constant to the right 4x= 72-4
Calculate it 4x=68
Then divide both sides by the x value x=68/4

Answer: x=17
