1/5 1/2x+9+6=5 how many solution are there to the equation

There is only one solution of x = 12

1/5(1/2x+9+6)=5

1/2x+15=25

1/2x=10

x=20

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
