# In Exercises 1-6, solve the system of linear equations. { − x + 8 y   =   − 2 4 x   − 9 y   =   5

To determine

To calculate: The system of linear equations which are 4x9y=5,and x+8y=2.

Explanation

Given Information:

The system equations are,

4x9y=5x+8y=2

Formula used:

Step 1: Write the given system of linear equation.

Step 2: Find the value of x from one of these two equations.

Step 3: Put that value of x in another equation.

Step 4: Solving that equation find y.

Step 5: Putting that value of y in the equation of x find the value of y.

Calculation:

Consider the system of given equations

4x9y=5x+8y=2

From the above equation,

x+8y=2x=28yx=2+8y

Putting this value of x in the equation 4x9y=5,

4x9y=54(2+8y)9y=58+32y9y=5
