Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
So we start off with what 4 numbers added together equal 32.
first truck 5 tons
second truck 7 tons
third truck 9 tons
and fourth truck 11.

5+7= 12 +9 = 21+11= 32.
-18+4x
2(2x-9)
4x=18
-4x=-18
x=18/4
-x=-18/4
