Desmos is Function Calculator is a great tool for this, the correct answer is z= 7/3

7/3= 2.333~ and so √(3*2.333~) + 2= 2.9999999833333~

Now 7- 2.9999999833333~= 4.0000000166667~ but I don't know the true infinate sign for this so thats why my numbers look a little werid, just plug (7/3) in for z and you will get 4, trust me

Use substitution to solve each system of equations Y=2x-2 Y=x+2

Alik [6]

Y = 2x - 2 ⇒ 2x - y = 2 ⇒ 2x - y = 2
y = x + 2 ⇒ x - y = -2 ⇒ 2x - 2y = -4
 3y = 6
 3 3
 y = 2
 2x - 6 = 2
 +6 +6
 2x = 8
 2 2
 x = 4
 (x, y) = (4, 2)
