You can put this solution on YOUR website!
In this problem you must first solve the x-15=32 equation
x=32+15
x=47
then you have to solve the other equations to see in which one x does not equal 47
first off you know d is not the solution as it states x=47
for a)
x+5=52
x=52-5
x=47
b)
x-20=27
x=20+27
x=47
c)
x-13=30
x=13+30
x=33
and d as you know was x=47
so the only solution that did not equal 47 was c.
