Question

I need help. i’m failing geometry

Answer 1

x = 1 and y = 6

Explanation:

so the opposite sides are equal to each other, therefore

4x + 7 = 12x - 1

and y + 1 = 3y - 11

so for the xs

start by adding 1 to each side

4x + 8 = 12x

subtract 4x from both sides

8=8x

divide by 8

x=1

for the ys

subtract one from each side

y= 3y -12

subract 3y from each side

-2y=-12

divide by -2

y=6

Answer 2

4x +7 =12x-1
-7 from both sides
4x=12x-8
-12x from both sides
-8x=-8
x=1
for y
y+1=3y-11
-1 from both sides
y=3y-12
-3y from both sides
-2y=-12
y=6
