An equation is formed of two equal expressions. The correct option is C.
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The ordered pair that is a solution to the system of linear equations can be found as shown below,
6x + 5y = -7
Solving for y,
y = (-7-6x)/5
In the second equation substitute the value of y,
2x - 4y = -8
2x - 4[(-7-6x)/5] = -8
2x + (28/5) + (24x/5) = -8
10x + 28 + 24x = -40
34x = -68
x = -2
Since the only option in which the value of x is -2 is option C. It is the correct option.
Hence, the correct option is C.

Answer:
All are valid
Step-by-step explanation:
Px - 43 = -42x + Q (rearrange)
x = (Q+43) / (P + 42) <----Substitute options for P & Q into this equation to see which combination gives exactly 1 solution for x
A) P=42, Q = 42; x = (42+43) / (42+42) = 1.011 (only 1 solution = valid)
B) P=43, Q = -42; x = (-42+43) / (43+42) = 0.012 (only 1 solution = valid)
C) P=-43, Q = -43; x = (-43+43) / (-43+42) = 0 (only 1 solution = valid)
D) P=42, Q = 43; x = (42+43) / (42+42) = 1.023 (only 1 solution = valid)

Answer:
Angle T = 39
Step-by-step explanation:
Triangle WXY is the same as triangle VTU
Therefore the angles are the same as well so because angle T and angle X are equal they both have the same value
