Answer:
Step-by-step explanation:
3x = 39.....so instead of just subbing in all ur answer choices....just solve for x
3x = 39...divide both sides by 3, cancelling out the 3 on the left side
x = 39/3
x = 13 <=====
x=-2
the answers are a and d
x+x+x=3x and you can't add a constant (2) to a variable(3x) so it would just be 3x+2
23/100
