Question

(3x+15° +(8x+7°+(3+-16)

Answer 1

`x=(3)/(7)` Degrees

Explanation:

3x+15°+8x+7°+3x-16°

bringing the like terms together . Like terms are those terms which contains the same variable. Hence here we have 3x , 8x and 3x our like terms and the constant terms are also like terms

3x+8x+3x+15°+7°-16°

adding the similar terms and simplifying the constant terms

14x=22°-16°

14x=6°

Dividing both the sides by 14

`(14x)/(14)=(6)/(14)`

`x=(3)/(7)`
