Answer:
b= -11
Explanation:
For an equation to remain valid, what we do to the right- hand side of the equation should also be done to the left- hand side of the equation.
5b= -55
Since we are finding the value of b, we need to divide the right- hand side by 5 to obtain b from 5b. Thus, divide the left- hand side by 5 too.
b= -55 ÷5
b= -11
