50q-43=52q-81 Start with the given equation



50q=52q-81%2B43Add 43 to both sides


50q-52q=-81%2B43 Subtract 52q from both sides


-2q=-81%2B43 Combine like terms on the left side


-2q=-38 Combine like terms on the right side


q=%28-38%29%2F%28-2%29 Divide both sides by -2 to isolate q



q=19 Divide
