{ x = − 8 + y − 11 x + 9 y = 4 { x = − 8 + y − 11 ⋅ ( − 8 + y ) + 9 y = 4 { x = − 8 + y 88 − 11 y + 9 y = 4 { x = − 8 + y − 2 y = 4 − 88
{ x = − 8 + y − 2 y = − 84 / : ( − 2 ) { x = − 8 + y y = − 2 − 84 { x = − 8 + 42 y = 42 { x = 34 y = 42
The solution to the system of equations is x = 34 and y = 42 , which can be written as 34 , 42 . The solution is obtained by substituting and simplifying the equations step-by-step. The values of x and y satisfy both equations in the system.
