Find the solution of this system of linear
equations. separate the x- and y- values with a
comma. enclose them in a pair of parantheses.
-20x = -88 - 17y
7x = -61 - 17y

The solution is (1, -4)

Step-by-step explanation:

Given:

The pair of linear equations given are:

Subtracting equation (1) from equation (2), we get:

Now, plug in the value of 'x' in equation (1) and solve for 'y'. This gives,

Therefore, the solution is (1, -4)

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
