Question

Explain how to solve the equations 312.50 = a + 0.25a to find the value of a

Answer 1

First you have to combine like terms meaning you have to add a+0.25a getting
312.50= 1.25a then you have to divide 312.50 by the 1.25 getting a= 250

Answer 2

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

I hope this helps!
