solve

square root 5-2x + 5 =12
5-2x under the sqaure

square root ( 5 - 2 x ) + 5 = 12 Subtract both 5 to both sides

square root ( 5 - 2 x ) + 5 - 5 = 12 - 5

square root ( 5 - 2 x ) = 7 Square both sides

5 - 2 x = 49 Subtract 5 to both sides

5 - 2 x - 5 = 49 - 5

- 2 x = 44 Divide both sides by - 2

x = 44 / - 2

x = - 22
