Question

Help me please with this math problem

Answer 1

Answer:

$x=14$

Step-by-step 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....
