ANSWER:
x=4 and y= -1
Explanation:
Add these equations to eliminate y:
4x=6
Then solve 4x =16 for x:
4x=16
4x/4 = 16/4 (divide both sides by 4)
x=4
Now that we have found x lets plug it back in to solve for y.
Write down an original equation:
x-3y=7
Substitute 4 for x-3y=7:
4-3y=7
-3y+4=7 (simplify both sides of the equation)
-3y+4+ (-4) = 7+ (-4) (add -4 to both sides of the equation)
-3y = 3
-3y/-3 = 3/-3 (Divide both sides by -3)
y= -1

That’s a lot of zombies and I’m scared now.
We notice that the upper trapezoid is symmetric to the lower one & the line of symmetry should be a horizontal line (mirror line) where any point of the upper vertices should be at equal distance (perpendicular) with the related vertices of the lower one from this horizontal line:
Note that QQ" =4 units, Hence the line of symmetry is the perpendicular to QQ' at 2 units
7/10=.7
.7+4=4.7
that is the answer
