Question

Use transformations to solve the equation.

-9b = -45

b = -9

b = -5

b = 5

b = 9

Answer 1

If you set b = 5, then the left side of the equation will be \[-9*5 = -45\], which is equal to the right side. Then you have solved it. Alternatively:\[-9b = -45 => b = \frac{ -45 }{ -9 } = 5\]

Answer 2

Remember that \[\frac{ -9b }{ -9 } = \frac{ -45 }{ -9 }\]
