Answer:
x = 11/2
Step-by-step explanation:
We would first put it in an equation
5x - 1 = 10 + 3x
We would first add 1 on both sides
5x = 11 + 3x
Then we subtract 3x on both sides
2x = 11
Divide both sides by 2
x = 11/2
Divide both sides by x + b to get m by itself. The equation will look like this: m = 
Total amount paid by Chris = 4000 + (22500 - 4000)(1 + 0.03)^5 = 4000 + 18500(1.03)^5 = 4000 + 21446.57 = $25446.57
Total amount paid by John = 5000 + (22500 - 5000)(1 + 0.12)^5 = 5000 + 17500(1.12)^5 = 5000 + 30840.98 = $35,840.98
John paid $10,394.41 more than Chris.
Move everything to one side, it becomes negative
3x+4-4x-5
=-x-1
