Question

Find the value of 9u - 6 given that -2u+2=6

Answer 1

The value of 9u - 6 is -24

Explanation:

Let us solve the question

∵ -2u + 2 = 6

→ Subtract 2 from both sides to move 2 from the left side to the right side

∵ -2u + 2 - 2 = 6 - 2

∴ -2u = 4

→ Divide both sides by -2 to find the value of u

∵
`(-2u)/(-2)` =
`(4)/(-2)`

∴ u = -2

∵ The given expression is 9u - 6

→ Substitute u by -2 to find the value of the given expression

∴ 9u - 6 = 9(-2) - 6

∴ 9u - 6 = -18 - 6

∴ 9u - 6 = -24

∴ The value of 9u - 6 is -24
