what is the solution of the system of equations? y=4x+1 y=5x-9

i believe x = 10, just set the equations equal to one another
how exactly would you do that though? im completely lost :(
solving 2 equations means you want the y of one equation to be equal to y of the other, and the same for the x's
so
y = y
5x-9 = 4x+1
5x - 4x = +1 + 9
x = 10
sub that back into either of the originals

y = 4x+1
y = 4(10) + 1
y = 41

notice you would have gotten the same y had you subbed into the second

so x = 10, y = 41
