Algebra 1 Help How many solutions are there to the equation below?

one
220 = 2x - 12x

220 = -10x
- 22= x
this is a linear equation as the x is to power one

Unless there is a sq missing, this is a linear eq so it can only have 1 solution

220 = -10x
x = -22

2x - 12x = -10x
x = -22

1 solution!!

220 = 2x - 12x
220 = -10x
x = 220/-10
x = -22 (one solution)
(answer A)

To solve this first you must cmobine the like terms in the equation (2x - 12x) then set the equation to 0.

220 = 2x - 12x
220 = -6x
220 - 220 = -6x - 220
0 = -6x - 220

Because this equation has no squared terms, there is only one x-intercept, which is also the only solution.

one solution x=-22

R u sure u didn't forget that one of the x is raised to the second power?
If not then it has 1 solution as someone already answered to you. Otherwise please give the full question so we could help.
