Answer:
Step-by-step explanation:
312.50= a+0.25a
We need to combine like terms a=1. All variables without a value equal 1.
a+0.25a= 1.25a
312.50= 1.25a
Divide both sides by 1.25, since 1.25 is being multiplied by a.
a= 250

Answer:
16
Step-by-step explanation:
2x -2 = 10 + 20
2x -2 + 2= 10 + 20 + 2
2x = 32
x = 32/2 = 16
Plug this in, too.
2(16) - 2 = 10 + 20
30 = 30 and they are equal!
