Solve each equation. What am I doing wrong because the answer is suppose to be 11/2 and I don't get the answer. Here's what I'm doing...

Problem: 2x+1/4-3x-4/5=1/2
I get: 10x+5-12x-16=10
Which gives me -2x=21
My answer is -21/2
the correct answer is suppose to be 11/2

    The way you typed it ...

    2x+1/4-3x-4/5=1/2
    -x = 1/2 - 1/4 + 4/5
    -x = 21/20
    x = -21/10 or -1.05

    check:
    LS = 2(-1.05) + .25 -3(1.05) - .8 = .5
    RS = 1/2 = .5

    My answer works for the way you wrote the equation
    RS =
