What is the solution of x+y=2 and 2x+5y=16?
erica [24]
Remember in order to use elimination you must have opposite signs so lets make the x in equation one -2 so we can eliminate 
-2(x+y=2)
-2x-2y=-4
2x+5y=16
so we get 3y=12 now divide both sides by 3 to get
y=4
so now you must plug y into one of your equations
x+4=2  so now you must get red of the 4 by subtracting four from both sides so that x=-2
so the solution is (-2,4)

Jacque needs to buy some pizzas for a party at her office. She's ordering from a restaurant that charges a \$7.50$7.50dollar sig
Nikitich [7]

The inequality that can be used to represent the situation is 7.50 + 14x ≤ 60 where x ≤ 3.75

<h3>Inequality</h3>

  • Delivery fee = $7.50
  1. Cost of each pizza = $14
  • Budget = $60
  • Number of pizza = x

7.50 + 14x ≤ 60

14x ≤ 60 - 7.50

14x ≤ 52.50

x ≤ 52.50 / 14

x ≤ 3.75
