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
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
This can be simplified to 4x+4=72
Move the constant to the right 4x= 72-4
