Question

consider fhe system of equations. 3x+5y=20 x-y=4 which system of equations is equivalent to the given system?

Answer 1

To find an equivalent system of equations, multiply the second equation and manipulate the equations using addition or subtraction to eliminate one of the variables.

Step-by-step explanation:

The given system of equations is: 3x + 5y = 20 and x - y = 4.

To find an equivalent system of equations, we can manipulate the equations using addition or subtraction to eliminate one of the variables.

By multiplying the second equation by 5, we get: 5(x - y) = 5(4) ➔ 5x - 5y = 20.

Now, we have the system of equations: 3x + 5y = 20 and 5x - 5y = 20, which is equivalent to the given system.
