Is (1,1) a solution to this system of equations?

Question

8x+y=9
6x+12y=18

Answer 1

Let's plug in the values x=1 and y=1 into the equations and see if they satisfy the equations.

First equation: 8(1) + 1 = 9
8 + 1 = 9
9 = 9

Second equation: 6(1) + 12(1) = 18
6 + 12 = 18
18 = 18

Since both equations are true when x=1 and y=1, the point (1,1) is a solution to this system of equations.
