Assuming this is a system of equations, here is how to find x.

2x + 3y = 45
x + y = 10

Multiply x + y = 10 by 2 so you are able to use the elimination method.

2x + 3y = 45
2x + 2y = 20

Subtract.

y = 25

Now that we've found y, we can plug it in to find x.

x + 25 = 10

Subtract 25 from both sides.

x = -15

Solve the equation for y. Then find the value of y for each value of x. <br><br> y+2x=5; x= -1, 0, 4

antiseptic1488 [7]

Answer:

y = 3, y = 5, y = -1

Step-by-step explanation:

What you do is you substitute the x values into the x.

<em>y + 2(-1) = 5</em>

<em>y + -2 = 5</em>

y = 3

<em>y + 2(0) = 5</em>

y = 5

<em>y + 2(4) = 5</em>

<em>y + 6 = 5</em>

y = -1.

Monica [59]

At x=0 y=6 the y intercept. The rate is -0.25 so the equation is y=6-0.25x. The ordered pair is (x,6-0.25x).
