Answer:
x = 42
Step-by-step explanation:
Collect like terms (all x together and constants together)
4x + 12 = 180
4x = 180 - 12
4x = 168
x = 168 / 4
x = 42
Answer:
x = 42
Step-by-step explanation:
First add the values with variable x and put them to one side of the equation and then do the same thing for the values without x
; x + 3x = 180 - 7 - 5
; 4x = 168....then divide both sides by 4
; x = 42
