Subtract the equations

   x  +   y   = 3.5
-3x   -y     = -2.5
-----------------------
-2x + 0  =  1


Solve for x
-2x = 1
x = 1/(-2) = -1/2 = -0.5

Sub into 1st equation:
-0.5 + y  = 3.5
y = 3.5 + 0.5 = 4

Solution = (-0.5,4)

Solve 8z + 12 = 5z − 21
Mekhanik [1.2K]
z = -11

Steps:
8z+12 = 5z-21
Subtract 12 from both sides
8z+12-12 = 5z-21-12
Simplify
8z = 5z-33
Subtract 5z from both sides
8z-5z = 5z-33-5z
Simplify
3z = -33
Divide both sides by 3
3z/3 = -33/3
Simplify
z = -11

Hope this helps you! (:
