Answer:

[tex]x=-1\\\\y=9[/tex]

Step-by-step explanation:

Given Equations:

[tex]14x+5y=31[/tex]    Equation:1

[tex]2x-3y=-29[/tex]   Equation:2

Multiplying Equation:2 by '7' both sides:

[tex]14x-21y=-203[/tex]       Equation:3

Subtracting Equation:3 from Equation:1

[tex]14x+5y-(14x-21y)=31-(-203)\\\\14+5y-14x+21y=31+203\\\\5y+21y=31+203\\\\26y=234[/tex]

Dividing by '26' both sides:

[tex]y=234/26\\\\y=9[/tex]

Putting the value of 'y' in Equation:2

[tex]2x-3(9)=-29\\\\2x-27=-29\\[/tex]

Adding '27' both sides:

[tex]2x=-29+27\\\\2x=-2[/tex]

Dividing by '2' both sides:

[tex]x=-1[/tex]

The values are:

[tex]x=-1\\\\y=9[/tex]
