Answer:

x = 2

Step-by-step explanation:

when you set these two equations equal to each other, you plug in numbers for x until you find one that makes both sides of the equation equal.  For example, 2^x - 1 = -x + 5 if you plug a 2 in for x you get 4-1 = -2+5 and both sides of the equation are equal to 3
