Step-by-step explanation:
<h2>1)3.25x + -1.5y = 1.25</h2>
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '1.5y' to each side of the equation.
3.25x + -1.5y + 1.5y = 1.25 + 1.5y
Combine like terms: -1.5y + 1.5y = 0.0
3.25x + 0.0 = 1.25 + 1.5y
3.25x = 1.25 + 1.5y
<h2>2)13x-6y=10</h2>
13x + -6y = 10
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '6y' to each side of the equation.
13x + -6y + 6y = 10 + 6y
Combine like terms: -6y + 6y = 0
13x + 0 = 10 + 6y
13x = 10 + 6y

Answer:
Angle A is 46. Angle B is 134
Step-by-step explanation:
If two angles are supplementary, they equal 180 degrees. So in order to find the measure of each angle, you need to find out what x is, by setting both equations equal to 180.
So it would look a little like this:
6x-8+9x+53=180.
Group like terms together
15x+45=180
get x alone by subtracting 45 on both sides
15x=135
and divide by 15 on both sides
x=9
So now we figured out that x = 9. Now plug that number in for both equations to find the angles of both
6(9)-8
54-8
angle A is 46
9(9)+53
81+53
angle B is 134
And you can check your work by seeing if both angles actually add up to 180, by definition being supplementary
134+46.. is 180
So there you have it

Answer and Step-by-step explanation:
1/2x is positive and 2 is negative, so they cross each other perpendicularly, and the equation needs to be at -13 y, 0 x
The answer is y = -2x - 13
