Using the elimination method, what is x and y, I am mostly having trouble with the y part, please explain 2x - 4y = 28
-x + 6y = -14

x = 14 and y = 0

Step-by-step explanation:

Given that,

2x - 4y = 28 (1)

-x + 6y = -14 (2)

Multiplying equation (2) by 2.

-2x + 12y = -28 (3)

Adding equation (1) and (3).

2x - 4y + (-2x) + 12y = 28 + (-28)

-4y +12y = 0

y = 0

Put the value of y in equation (2).

-x + 6(0)= -14

x = 14

Hence, the solution of the equations are x = 14 and y = 0.

answer: 0.95, d

step-by-step explanation:

first, you have to combine the percentages of costumers ordering pizza or salad. 25% (percent of salads ordered) plus 70% (percent of pizzas ordered) is equal to 95%. then, turn 95% into a fraction: 95/100. lastly, divide 95 by 100 and you will get 0.95, d.
