we can only add like terms, so if we want to find the term with x we will add 8x + 4x

This will give us 12x

We then want to add our constants, or “normal” numbers, which means we will add -3+3 which will give us 0

so our simplified will be 12x + 0 = 180

(For just this question it will be 12)

Hey there!

8x - 3 + 4x + 3 = 180°


COMBINE the LIKE TERMS

(8x + 4x) - (3 + 3) = 180°

8x + 4x - 3 + 3 = 180°


12x + 0 = 180°

12x = 180°


DIVIDE 12 to BOTH SIDES

12x/12 = 180/12


CANCEL out: 12/12 because that gives you 1


KEEP: 180/12 because it helps solve for the x-value


NEW EQUATION: x = 180/12


SIMPLIFY IT!

x = 15


Therefore, your overall answer is: x = 15


The answer to your given question is:

12x + 0 = 180


Good luck on your assignment & enjoy your day!
