Question

Find the value of x
(7x - 12) 114

Answer 1

`(7x - 12) + 114 = 180`

Reason: The cointerior angles equal 180°

Collecting like terms:

`7x + 102 = 180 \\ 7x = 180 - 102`

`7x = 78`

Divide both sides of the equation by the coefficient of 7x which is 7.

`(7x)/(7) = (78)/(7)`

`x = (78)/(7) = \\ = 11.14`

( The decimal answer is not necessary except if asked for)

I hope this helps.

Answer 2

(7x-12)=-5

-5x÷-5 114÷-5=

x=29
