Multiply the second equation by 2 so that its
6x+4y=-30
then subtract
6x+y=-39
6x+4y=-30
= -3y=-69
divide by -3 to isolate the y
then you get y=23
substitute the y value back into one of the equations to solve for x.
6x+23=-31
solve like you always do and you'll get your x
Congratulations, you solved a problem.

Hope this helps!
Answer:
The slope of the equation is 2
Step-by-step explanation:
To isolate the y-variable by itself, divide both sides of the equation to get y = 2x - 3.
Since mx + b is how you graph a line, and the coefficient of x is the slope, 2 is the slope.

Answer:
<x = 20°
Step-by-step explanation:
<x = 1/2(arc UT - arc SV)
<x = 1/2(65° - 25°)
<x = 1/2 (40°)
<x = 20°
