(-5x+7y=11) - (-5x+3y=19) =
4y = -8. (divide both sides by 4)
y = -2
Substitute
-5x + 7(-2) =11
-5x - 14 =11
-5x = 25
x = -5
y = -2 and x = -5
The measure of angle A and C will be 94.5° and 85.5°.
<h3>How to calculate the angle?</h3>
(5y - 3) + (3y + 27) = 180
Collect like terms
5y + 3y - 3 + 27 = 180
8y = 180 - 27 + 3
8y = 156
y = 156/8 = 19.5
(5y - 3) = (5 × 19.5) - 3 = 94.5
(3y + 27) = (3 × 19.5) + 27 = 85.5
Therefore, the measure of angle A and C will be 94.5° and 85.5°.

You'd first change the equation to slope-intercept form.
For example:
-2x + y = 6
You'd add 2x to both sides -
-2x + y + <u>2x</u> = 6 + <u>2x </u>
y = 2x + 6
So you'd graph y = 2x + 6
