OpenStudy (anonymous):

OpenStudy (anonymous):

-9?

OpenStudy (dtan5457):

OpenStudy (anonymous):

how?

OpenStudy (anonymous):

OpenStudy (dtan5457):

4x=2x+18 subtract the 2x 2x=18 x=..?

Am i right?

OpenStudy (dtan5457):

no. to see this better, what times 2 equals 18?

OpenStudy (dtan5457):

2(x)=18 x represents the missing number

9

OpenStudy (anonymous):
