Answer:
12
Step-by-step explanation:
get both x 's on the same side of the equation, 60= 9x-4x
then combine like terms so...
60=5x
do 60÷5=12
to get x alone so x=12
Put a point on the number 125 put a point on the number -12 and put a point on the number -2110
I’m kinda confused by this question but
Hope that helped :)
