Step 1

Let the first number be x and the second number by y.

Addition of three times the first number with twice the second number gives 8.

Thus, 1)$3x+2y=8$

Subtraction of the second number from two times the first number gives 3.

Thus,

2)$2x-y=3$

Multiply equation (2) by 2

3)$4x-2y=6$

Step 2

Add equations (1) and (3)

$3x+2y+4x-2y=8+6$

$7x=14$

$x=2$

Put the value of x in the equation (1)

$6+2y=8$

$2y=2$

$y=1$

The systems of the equation are$3x+2y=8$ and $2x-y=3.$

The solution of the equations is$(x,y)=(2,1)$ .

Let the first number be x and the second number by y.

Addition of three times the first number with twice the second number gives 8.

Thus, 1)

Subtraction of the second number from two times the first number gives 3.

Thus,

2)

Multiply equation (2) by 2

3)

Step 2

Add equations (1) and (3)

Put the value of x in the equation (1)

The systems of the equation are

The solution of the equations is
