r%2F2-8=-4 Start with the given equation



%282%29%28r%2Fcross%282%29-8%29=%282%29%28-4%29 Multiply both sides by the LCM of 2. This will eliminate the fractions (note: if you need help with finding the LCM, check out this solver)



r-16=-8 Distribute and multiply the LCM to each side



r=-8%2B16Add 16 to both sides


r=8 Combine like terms on the right side
