13 people are required to do so
9x+12=5x+4
9x-5x=12-4
4x=8
x=8/4
x=2
Answer:2
Step-by-step explanation:
rs + st = rt Plug in the values
3x + 1 + 2x - 2 = 64 Combine like terms (1 and -2)
3x -1 + 2x = 64 Combine like terms (3x and 2x)
-1 + 5x = 64 Add 1 to both sides
5x = 65 Divide both sides by 5
x = 13
