3z-t=4 3z+t=8

To solve this system of equations, we can use the method of substitution.

First, let's rewrite the equations:

1. 3z - t = 4
2. 3z + t = 8

Now, let's solve the system step by step:

1. Add the two equations together to eliminate t: (3z - t) + (3z + t) = 4 + 8 6z = 12 z = 2

2. Substitute the value of z back into one of the equations to find t: 3(2) - t = 4 6 - t = 4 t = 2

So, the solution to the system of equations is: z = 2 t = 2

Данная система уравнений имеет решение: z = 2 t = 2
