Thread: Need help solving this problem with fractions

Can someone help me and give me a step by step to solve the following?

147/20/2-x = 147/10

So 147 over 20 over 2-x equals 147 over 10.

Please correct me if I'm wrong. It sounds like your equation is


If that's correct first note that you can cancel out the 147 from both sides. That leaves you with


Flip this equation upside down and solve for x

147/20/2-x = 147/10

147/20 ÷ (2-x) = 147/10
147/20 × 1/(2-x) = 147/10
147/20(2-x) = 147/10 divide by 147 to both sides
1/20(2-x) = 1/10
20(2-x) = 10 ---------- divide by 10
2(2-x) = 1
4 – 2x = 1
2x = 3
x = 3/2

Is there an echo in here?
