Answer:
33x-44
Step-by-step explanation:
15x-20-24+18x
33x-44
Answer:
y=15
x=43
(any variable can be used, I used x and y to make it easier to show)
Step-by-step explanation:
x+y=58
x-y=28
get x by its self
x=58-y
then subsitute into the other equation
(58-y)-y=28
58-2y=28
-2y=-30
y=15
sub. again
x+15=58
x=43
-3-4(5)
-4(5)=-20
-3-20
