Answer:
y = -
Step-by-step explanation:
slope-intercept form : y = mx + b
Solve for y.
Subtract 3x on both sides. You get --> 7y = -3x - 14
Divide by 7 on both sides. You get --> y = 
Simplfy it. -14/7 = 2 so you get y = -
Answer:
x = 34
Step-by-step explanation:
The angles x + 12, 100, and x add up to a straight angle, so the sum of their measures is 180°.
(x + 12) + (100) + (x) = 180
x + 12 + 100 + x = 180
2x + 112 = 180
2x = 68
x = 34
