Will someone walk me through this?

(Solve by elimination)

Equation 1 : 7x - 2y = 37

Equation 2: 4x + y = 19

x = 22.75 & y = - 15

Step-by-step explanation:

The equations are;

7x - 2y = 37 (equation 1)

4x + y = 19 (equation 2)

Now multiplying equation 1 by 4,

28x - 8y = 148 (equation 3)

Now multiplying equation 2 by 7,

28x + 7y = 133 (equation 4)

Subtracting equation 3 with with equation 4,

we get x = 22.75 & y = - 15
