⚠️ Urgent PLS HELP !!! find the value of x.

Mathematics
1 answer:
jok3333 [9.3K]3 years ago
5 0

Answer:

x = 14.5

Step-by-step explanation:

This is a supplementary angle, meaning the sum of the angles is 180°.

We can find the value of x by combining like terms.

5x - 6 + 7x + 12 = 180.

5x and 7x are alike.

5x + 7x = 12x.

-6 + 12 = 6.

The final equation is 12x + 6 = 180.

We can solve this by subtracting 6 from 180.

180 - 6 = 174.

12x = 174

Lastly, we divide 174 by 12.

174 / 12 = 14.5

Therefore, x is equal to 14.5
