Question

Help me please with this math problem

Answer 1

`x=14`

Explanation:

`(5x-14)+(8x+12)=180`

These two angles on the line is 180°

Solve the equation:

`5x-14+8x+12=180`

`5x+-14+8x+12=180`

`(5x+8x)+(-14+12)=180` {combine the like terms}

`13x-2=180`

`13x=180+2`

`13x=182`

`x=182/13`

`x=14`

PROOF:

{substitute 14 in the place of x}

`(5(14)-14)+(8(14)+12)=180`

`56+124=180`

`180=180`

hope this helps....
