Answer:
angle 1: 72.5°
angle 2: 107.5°
Step-by-step explanation:
x + y = 180
x - y = 35 ===> x = 35 + y
Substitution to find angle y:
x + y = 180
(35 + y) + y = 180
35 + 2y = 180
2y = 145
y = 72.5
Substitution to find angle x:
x = 35 + y
x = 35 + (72.5)
x = 107.5

Step-by-step explanation:
First convert from standard to slope intercept form.
3x+4y=12
4y=-3x+12
y=-3/4x+3
The slope should be -3/4 and the y intercept should be 3.
