Question

solve for the value of x will Mark brainious there's two questions left and I appreciate every one of y'all for helping 7x+9 5x+3 theres 5 answers 12 13 14 15 which one you are all so amazing 2 questions left ty all​

Answer 1

14

Explanation:

By applying the vertical angle theorem to 5x + 3, using same-side exterior angle theorem, we can find that:

(7x + 9) + (5x + 3) = 180

Now to find x, we can just solve for x in the equation we found.

(7x + 9) + (5x + 3) = 180

Combine like terms.

12x + 12 = 180

Subtract 12 from both sides.

12x = 168

Divide both sides by 12.

x = 14

So the value of x would be 14.

I hope you find my answer and explanation to be helpful. Happy studying.

Answer 2

x = 14

Explanation:

7x + 9 + 5x + 3 = 180

7x + 5x = 180 - 3 - 9

12x = 168

x = 168 / 12

x = 14
