2%2F5=%28x-2%29%2F20 Start with the given equation



%2820%29%282%2F5%29=%2820%29%28%28x-2%29%2F20%29 Multiply both sides by the LCM of 20. This will eliminate the fractions (note: if you need help with finding the LCM, check out this solver)



8=x-2 Distribute and multiply the LCM to each side



0=x-2-8Subtract 8 from both sides


-x=-2-8 Subtract x from both sides


-x=-10 Combine like terms on the right side


x=%28-10%29%2F%28-1%29 Divide both sides by -1 to isolate x



x=10 Divide
