Answer:
The answer is - 9
Step-by-step explanation:

The correct answer would be 616
Answer:
2x+20+3x+10 = 180 (int. angles, parallel)
5x+30 = 180
5x=150
x=30
Multiply the equation 2x + y = 1 by 3 to obtain same coefficients of y.

Substract the equation 3x + 3y = 15 from 6x + 3y = 3 to eliminate the terms of y.

Substitute -4 for x in the equation 2x + y = 1 to obtain the value of y.

So solution of equations is (-4,9).
