Question

How many solutions can be found for the equation 5x + 3(x − 1) = 10x − 2x − 3?

None
One
Two
Infinitely many

Answer 1

First solve the equation:
5x + 3(x - 1) = 10x - 2x - 3

Start with 3(x - 1) what is that?

Answer 2

idk what x is

Answer 3

your just multiplying it so it would be 3x-3

Answer 4

um

Answer 5

the x is confusing me

Answer 6

first you have to simplify each side which is 5x+3x-3=10x-2x-3
Then you combine like terms so its 8x-3=8x-3. Since both sides are identical, there are infinite solutions

Answer 7

Now, you have 5x - 3x - 3 = 10x - 2x - 3

Answer 8

Put all the same type variables on one side:
5x - 3x - 2x + 10x = -3 - 3

Answer 9

Now simplify that:
10x = -6

Divide 10/6 = 1 2/3
No solution.
