The triangle is always 180 degrees
6x + 8x + 7 + 8x - 3 = 180
Simplify
22x + 4 = 180
Minus 4 from both sides
22x = 176
Divide 22 by both sides
X = 8
Can I get brainliest answer

Answer:

x = 8

Step-by-step explanation:

All angles of a triangle must add up to 180 degrees.

So 8x + 7 + 6x + 8x - 3 = 180

Combine like terms

22x + 4 = 180

Subtract 4

22x = 176

Divide

22x ÷ 22 = 176 ÷ 22 = x = 8

We can make sure this is correct by plugging in 8 for all x terms.

8(8) + 7 + 6(8) + 8(8) -3

64 + 7 + 48 + 64 - 3 = 180.

X = 8

Hope this helps.
