Q. Is (1,1) a solution to this system of equations?8x+y=96x+12y=18Choices:[[yes][no]]
Plug and Verify First Equation: First, let's plug x=1 and y=1 into the first equation: 8x+y=9. So, 8(1)+1=9. That's 8+1=9. 9=9, looks good.
Check Second Equation: Now, let's check the second equation: 6x+12y=18. Substitute x=1 and y=1 into it: 6(1)+12(1)=18. That gives us 6+12=18. 18=18, that's right too.
