# Solve the system of equations below using the substitution method. x = y + 7 / 2 4x − 2y = 8 natalie407888

x = 3 ± √(5+y) montgomerykarloxc24x

idk

step-by-step explanation: beautycutieforever10

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
