y = 3 x 2 (1)
y = 2 x 5 y (2)
Since both expressions 3x-2 and 2x-5 are equal to y, set them equal to each other forming an equation in terms of x
3 x 2 = 2 x 5
Subtract 2x on both sides
3 x 2 x 2 = 5
Add 2 on both sides
3 x 2 x = 5 + 2 x = 3
Substitute the value of x into equation y = 3 x 2
y = 3 × ( 3 ) 2 y = 9 2 y = 11 ( x , y ) = ( 3 , 11 )
