The constant of variation is 18/4 = 9/2= 4.5
Answer:
2z-31 = -9z+24
First, combine like terms: 11z = 55
Then, divide both sides by 11: 11z/11 = 55/11
Simplify: z=5
Step-by-step explanation:
11a:
3x+5=5x-57
3x-5x=-57-5
-2x=-62
x=31
11b:
2x+2x+4x+150+4x+150=360
12x+300=360
12x=360-300
12x=60
x=5
hope this helped !!
