Question

Solve each equation below. Show your work! a) 2 = 169 b) 3 = −125

Answer 1

a)

`{ \tt{2x = 169}}`

• divide all sides by 2 following division property of equality:

`{ \tt{ (2x)/(2) = (169)/(2) }} \\ \\ { \tt{ \underline{ \: \: x = 84 (1)/(2) \: \: }}}`

b)

`{ \tt{3x = - 125}}`

• divide all sides by 3 following division rule of equality:

`{ \tt{ (3x)/(3) = ( - 125)/(3) }} \\ \\ { \tt{ \underline{ \: \: x= -41.67 \: }}}`
