Subtract to isolate b: We have the equation 49=16+(73)b. To isolate b, we should first subtract 16 from both sides of the equation.Calculation: 49−16=16+(73)b−1633=(73)b
Multiply by reciprocal to solve: Now we have 33=(73)b. To solve for b, we need to multiply both sides by the reciprocal of (73), which is (37).Calculation: 33×(37)=(73)b×(37)77=b
