Question

Y=x-2
y=4
x=3
y=2x+1
CAN SOMEBODY HELP ME WITH THIS? SUPER HARD HOMEWORK​

Answer 1

//Solve equation [2] for the variable y

[2] y = 4

// Plug this in for variable y in equation [1]

[1] (4) - x = -2

[1] - x = -6

// Plug this in for variable y in equation [4]

[4] (4) - 2x = 1

[4] - 2x = -3

// Solve equation [1] for the variable x

[1] x = 6

// Plug this in for variable x in equation [3]

[3] (6) = 3

[3] 0 = -3 => NO solution

No solution
