    What is the value of x?

    x+y=62

    2x+(1/2)y=88

    How can I find the value of x?

    x + y = 62 ; y = 62 - x [1]

    2x+(1/2)y=88 ; multiply by 2: 4x + y = 176 [2]

    Substitute [1] in [2] and solve for x.

    Thanks Wilmer.

    I got it down to 4x+(62-x)=172 but I'm unsure of how to continue from here...

    y = 62 - x
    4x + y = 176

    => 4x + 62 - x = 176
    => 3x = 114
    => x = 38

    sub the x into the first equation to find y.
