Answer:
31 1/3
Step-by-step explanation:
3x-10=84, given
3x=94, add 10 to both sides
x = 31 1/3, divide both by three
-3(x - 2) = 2(x - 7) remove the parentheses
-3x + 6 = 2x - 14. Move the terms
-3x - 2x = -14 - 6. Collect like terms. Calculate.
-5x = -20. Divide both sides.
Solution: x = 4
18%, because 50 - 100, meaning 1 is 2% so 9x2 is 18
