Write the problem as a mathematical expression.

6y+2z=-5
4y+2z=3

Solve for y in 6y+2z=-5.

y=-56-z3

4y+2z=3

Replace all occurrences of y with -56-z3 in each equation.

-2(5-z)3=3

y=-56-z3

Solve for z in -2(5-z)3=3.

z=192

y=-56-z3

Replace all occurrences of z with 192 in each equation.

y=-4

z=192

List all of the solutions.

y=4,z=192
