Answer: 30
Step-by-step explanation:
x = - 36
multiply both sides of the equation by - 2
x = (- 2)× 18 = - 36
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
$260.00
Because you won’t need to multiply the $60.00 per person
