2 answers:
Answer:
It has one solution
Step-by-step explanation:
4x + 8 = −2 − 2 + 5x
collect like terms
if + 5x goes to the left sides it become - 5x and if + 8 goes to the right sides it becomes - 8
4x - 5x = -2-2-8
add the values on both sides
-x = - 12
divide both sides by -1
x = 12
It has one solution. The only solution is if x = 12.
