To Solve: The given system of linear equations by elimination and check the solution.

9x+y=2−4x−y=−17

Expert Solution & Answer

Answer to Problem 4E

The required solution is x=−3,y=29

Explanation of Solution

Given information:

9x+y=2−4x−y=−17

Calculation:

9x+y=2 Equation 1−4x−y=−17 Equation 2

Variable y can be eliminated by adding equation 1 and 2

9x+y=2 −4x−y=−17 _ 5x =−15

Divide 5 on both sides

⇒5x5=−155⇒x=−3

Now substitute the value of x in equation 2

⇒−4⋅(−3)−y=−17⇒12−y=−17

Subtract 12 from both sides

⇒12−12−y=−17−12⇒−y=−29⇒y=29

Check

Right hand side of equation 1 is 2

Left hand side of equation 1 is 9x+y=2

Substituting the known value and simplify

=9⋅(−3)+29=−27+29=2

Left hand side = Right hand side.

Right hand side of equation 2 is -17

Left hand side of equation 2 is −4x−y=−17

Substituting the known value and simplify

=−4⋅(−3)−29=12−29=−17

Left hand side = Right hand side.
