%288%2F7%29x=-12 Start with the given equation


cross%28%287%2F8%29%288%2F7%29%29x=-12%287%2F8%29 Multiply both sides by %287%2F8%29 to eliminate 8%2F7 on the left side


x=-84%2F8%29 Multiply


x=-21%2F2%29 Reduce


So our answer is x=-21%2F2%29 which is x=-10.5 in decimal form

8/7x=-12
1st in all problems with fractions and equal signs (equations): FIRST, GET RID OF THE FRACTIONS !!!
multiply 7 times both sides: 8x=-84
get rid of the 8; divide 8 into each side: x=-84/8=-21/2
