x = 3 ± √(5+y)

idk

step-by-step explanation:

y = -3

x =

Step-by-step explanation:

4(y + ) - 2y = 8 Distribute the 4. Multiply everything in the parentheses by 4

4y + 14 - 2y = 8 4 = = 14 Combine the like terms 4y and -2y

2y + 14 = 8 Subtract 14 from both sides

2y = -6 Divide both sides by 2

y = -3

Plug -3 in for y in either original equation.

4x - 2y = 8

4x -2(-3) = 8

4x + 6 = 8 Subtract 6 from both sides

4x = 2 Divide both sides by 4

x = =

Check:

x = y +

= -3+

= +

=

4x - 2y = 8

4() - 2(-3) = 8

2 + 6 = 8

8 = 8
