x+1divided by 8=x/4

Question

Solve equation, write a justification for each step, and check solution.

Answer 1

(x+1)/8=x/4

there are different things you can do now...

you can cross multiply

4(x+1)=8x

4x+4=8x

4x-4x+4=8x-4x

4=4x

x=4/4

x=1

(1+1)/8=1/4

2/8=1/4

1/4=1/4

you can multiply x and 4 both by 2 to get 2x/8

now both denominators are equal so both numerators must be equal

x+1=2x

x-x+1=2x-x

1=x
