Question

What is the value for x

Answer 1

Those are adjacent angles. They will equal 180 degrees since they both ly on the same straight line. Straight line= 180 degrees.

10x-20+6x+8=180

Add 20 to both sides.

10x+6x+8= 200

Combine like terms.

16x=192

Divide both sides by 16.

x=12

Answer 2

10x - 20 + 6x + 8 = 180

16x - 12 = 180

16x -12 (+12) = 180 (+12)

16x = 192

16x/16 = 192/16

x = 192/16

x = 12

hope this helps

note: a straight line is equal to 180° *
note: you must add the two together and equal it to 180° to get x at the end*
