Answer:
y=1; x=2
Step-by-step explanation:
Substitution:
x=2y
2x+5y=9
=> if x=2y, plug in the x value into other equation, so
----------------------------------------------------------------------------
2(2y)+5y=9
4y+5y=9
9y=9
y=1
You have the Y value, so now solve for X
-----------------------------------------------------------------------
plug in y value to x=2y
so x=2(1)
x=2
Answer:
315
Step-by-step explanation:
Area = Length x Width
Area = 21 x 15
Area = 315
Y - 8 =(-8/9)(x - 3)
y - 24/3 = (-8/9)x + 8/3
y = (-8/9)x + 32/3
