Hi there,
when 3 is added to a number and the result is multiplied by 5.
You obtain 1 less than the number you started with.
Make the number = 'x'
5(3 + x) = x - 1
Multiply out
15 + 5x = x - 1
Collect like terms:
5x - x = -1 - 15
4x = -16
x = -4
Proof:
5(3 + x) = x - 1
5(3 - 4) = -4 -1
5(-1) = -5
-5 = -5
Number is -4.
Hope this helps :-)
