x = 1, y = 2

Step-by-step explanation:

9x - 4y = 1 Equation 1

-8x - 7y = -22 Equation 2

-(8x+7y) = -(22) I have inserted an extra equation here so that it is easier to see how I did the next step.

Equation 2 × (-1): 8x+7y = 22 Equation 3

When an equation is multiplied by (-1), the -signs can be removed as two - makes one +. This applies to both sides of the equation.

Equation 1 × 22: 198x - 88y = 22 Equation 4

Now, Equations 3 and 4 have the same total, that means that they equal to each other.

8x+7y = 198x - 88y

Evaluate by putting the expressions with x on one side and expressions with y on the other side.

7y+88y = 198x-8x

Further evaluate.

95y = 190x

Further simplify by dividing both sides by 95.

y = 2x Equation 5

Now we can substitute y = 2x into equation 1.

9x - 4(2x) = 1

Evaluate.

9x - 8x = 1

Further evaluate.

x = 1 Equation 6

Substitute x = 1 into equation 5.

y = 2(1)

Evaluate.

y = 2
