Answer:
Ok what's your question? cna you include the graph?
A = 7 and x = -5
-a + 3x = -(7) + 3(-5) = -7 -15 = -22
Answer: -22
Answer:
The Slope of AB: 5/1
The Slope of DC: -1/5
The Slope of BC: 2/3
The Slope of AD: 2/3
The quadrilateral is a trapezoid because BC and AD are parallel to each other while AB and DC are congruent.

Answer:
y = 5 -x
6x +3(5 -x) = 27
Step-by-step explanation:
The first equation is conveniently solved for either x or y. If we solve it for y, we get ...
y = 5 - x . . . . . . subtract x from both sides
This expression for y can be substituted into the second equation to give ...
6x +3(5 -x) = 27
These are your new system of equations.
Simplified, they are ...
_____
The second is a 2-step equation that gives the value of x, which can then be used in the first equation to find y.
3x = 12 . . . . subtract 15
x = 4 . . . . . . divide by 3
y = 5 -4 = 1 . . . . substitute into the first equation
The solution is (x, y) = (4, 1).
