    3/4(x+4)=10 is this the problem?

    3/4x + 4 = 10 subtract 4 from both sides 3/4x = 6 |dw:1363805836196:dw|

    The question is: (3/4)x + 4 = 10 (where / means division) You want to isolate for x by essientially doing bedmas/pedmas in reverse. Subtract 4 from both sides: (3/4)x + 4 - 4 = 10 - 4 (3/4)x = 6 Divide both sides by (3/4): (3/4)x/(3/4) = 6/(3/4) x = 6/(3/4) Recall that dividing by a faction is the same as multiplying by the reciprocal fraction(ie flipped fraction) : x = 6 * (4/3) Multiply numerator with numerator and denominator with denominator: x = (6/1) * (4/3) x = (6 * 4)/(1 * 3) x = 24/3 x = 8
