The interest earned on a deposit of $800 at 5.5% annual
interest rate for 3 years.

answer: 12

step-by-step explanation:

because yes

you can't solve x because it is 2 linear equation and you only have one equation

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
