Answer:
(-4,4)
Step-by-step explanation:
-5x-10y=-20
10x+10y=0
divide both sides by 2
-5x-10y=-20
5x+5y=0
that makes
-5y=-20
divide both sides by -5
y=4
now substitute 4 for y
10x+10 x 4=0
multiply
10x+40=0
subtract
10x=-40
divide
x=-4
Answer:
a = 28
b = 87
Step-by-step explanation:
By definition, opposite sides of a parallelogram are equal. So we can set the two expressions equal and solve for a:
a - 10 = 18
a = 28
Also by definition, opposite angles of a parallelogram are congruent. So set those two expressions equal and solve for b:
b + 16 = 103
b = 87
