4/5=n/15 what is n
Subject: Basic Math
SOLVE: 5(-3X-2) -(X-3)=-4(4X+5)+13
SOLUTION FACTORS: -15X-10-X+3=-16X-20+13 Let's add and subtract: -16x-7=-16x-7 Now we can see both sides are equal, but we can prove it by moving each equation to the other side that: -16x+16x=-7+7 once moved, the positive becomes negative and the negative becomes positive. 0=0 and here we prove that the equations are equal to each other.
