- 25. Multiple ChoiceWhat is the solution to this system?
y = x
3x - 2y = 3(1,1)(3,3)(-2,0)(0,-2) - 26. Multiple ChoiceCHALLENGE: Three equations.
x + y + z = 4
x = -2y
z = -3y
Solve the system of equations using substitution.x = 2
y = -1
z = 3x= -5
y = 3
z = 1x = 10
y = -2
z = 0x= 4
y = 1
z = -1 - Answer choicesTagsAnswer choicesTags
