How many solutions does -10x+x=-9x have

A) one solution

B) two solutions

C) No solutions

D) infinite solutions

I am not sure but i think B so two solutions

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
