What is the missing number in the equation?
5×17−112−14?=−27.5
We place the multiplication exercise inside of the parenthesis:
(5×17)−112−14x=−27.5
We solve the multiplication exercise and then subtract:
85−112−14x=−27.5
−27−14x=−27.5
We swap sections:
−14x=−27.5+27
−14x=−21
We multiply by 14:
−x=−21×14
−x=−7
We multiply by -1
x=7
