Answer:
Y=20
Step-by-step explanation:
90= (4y+10)
90-10=4y
80=4y
Y=80/4= 20
The answer is that x=4:) comment if you want the steps
Answer:
change the equation into one variable.
2 y equals 10 + x
y equals 5 + x by 2
now put that into the second equation
-3x + b parentheses 5 + x / 2 equals 11
-3x+b(5+ x/2)
-3x + b5 + bx/2 = 11
Diagonals of a parallelogram bisect each other. It is not relevant that PN=9. since AO=4 then AM=4
