Plug 4x=9 in for y:
10x=18-2(4x+9)
10x=18-8x-18
10x=-8x
18x=0
x=0
now plug 0 in for x:
y=4(0)+9
y=9
to check, plug x and y back into one of the equations to make sure they are right:
10(0)=18-2(9)
0=18-2*9
0=18-18
0=0
Answer:
(- p) × (- p) × (- p)
Step-by-step explanation:
(-p)³
(- p) × (- p) × (- p)
P=2L+2W
1. Subtract 2L from both sides
P-2L=2W
2.Divide both sides by 2 to isolate "W"
P-2L/2=W
3.Flip the equation
W=P-2L/2
So solution is
W=P-2L/2
