I please need help with these two questions please! I promise brainliest, and there's a link for the screenshot. I need help ASAP!

The lines shown below are parallel. if the green line has a slope of -1, what is the slope of the red line

If the measure of angle 1 is 110 degrees and the measure of angle 3 is (2 x+10 degree), what is the value of x?

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?
