Answer:

x=35

Explanation:

Angles on a straight line=180

therefore,(2x-5)+(3x+10)=180

2x-5+3x+10=180

collecting like terms we have,

2x+3x-5+10=180

5x+5=180

subtract 5 from both sides

5x+5-5=180-5

5x=175

divide both sides by coefficient of x

5x/5=175/5

x=35

Answer:

x=35

Explanation:

So the line XYZ is 180. The angles together should equal 180 in total.

The equation would be (2x-5) + (3x+10) = 180.

2x-5+3x+10=180

You want to combine like terms.

2x+3x and -5+10

5x+5=180

subtract 5 from both sides. Need variable alone.

5x+5(-5)=180(-5)

5-5 is 0 and 180-5 is 175

5x=175

Divide by 5 on both sides.

5x/5=175/5

x=35
