answer:
x = 4
y = 19
step-by-step explanation:
- we know that this is a parallelogram, so opposite sides are equal
- this is one of the properties of a parallelogram
therefore,
segment AB = segment DC <em>and</em> segment AD = segment BC
- now plug in the expressions according to what we know (& solve)
AB = DC
5x - 13 = 9x - 29
-13 = 4x - 29
16 = 4x
x = 4
AD = BC
3y - 11 = 2y + 8
y - 11 = 8
y = 19
Answer is c
Hope this helps :)
Answer:
x= -1
Step-by-step explanation:
the equation would be written like this
2+16x= -7x-21
add -7x on both sides
2+23x= -21
subtract 2 from each side
23x= -23
divide by 23 on both sides
x= -1
