Systems of linear equations ; elimination method pls < 3

10x + 25y = 11,700

2x + 3 = y

Elimination method:

Isolate the number from the variables:

10x + 25y = 11,700

2x - y = -3

Multiply the second equation by 5 to eliminate x:

10x + 25y = 11,700

10x - 5y = -3

Subtract:

30x = 11,703

Divide by 30:

x = 390.1

Plug x back in.

3901 + 25y = 11,700

Isolate y:

25y = 7802

y = 312.08
