so use distributive property which is a(b+c)=ab+ac so 1/2(x+20)=1/2x+10
and the other 4(6-x)=24-4x
so now we have 1/2x+10=17/4x+24-4x convert -4x to -16/4x and add to the 17/4x 1/2x+10=1/4x+24 subtract 24 from boths ides 1/2x-14=1/4x multily both sides by 4 2x-56=x subtract x from both sides x-56=0 add 56 to both sides x=56
