7y^2+15x-22. Y=4. ×=5

Nutka1998 [239]

let's plug the value of x and y as 5 and 4 respectively to find the value of given expression :

$7 {y}^{2} + 15x - 22$

$7(4) {}^{2} + (15 \times 5) - 22$

$(7 \times 16) + 75 - 22$

$112 + 53$

$165$

Solve the systems of equations by substitution.<br> 2x+y=-2<br> 3x-y=7

lukranit [14]

Answer:

To solve the system of equations by substitution:

<u>2x+y=-2</u>

<u>3x-y=7</u>

first solve for y:

2x+y=-2

y=-2x-2

Then plug ^^ equation for y in the other equation

3x-(-2x-2)=7

5x+2=7

5x=5

x=1

Then solve for y:

2(1)+y=-2

y=-4

Final answer is x = 1 and y = -4

Hope it helps!
