Question

Solve the equation: 3x - x + 2 = 4(2x - 1) infinite solutions x = 1 x = -1 no solution

Answer 1

X = 1

Porque:

3x - x + 2 = 4(2x - 1)

3x - x + 2 = 8x - 4

3x - x - 8x = - 4 - 2

- 6x = - 6

x = - 6/ -6

x = 1 ✔️

Answer 2

`x=1`

B

Explanation:

So we have the equation:

`3x-x+2=4(2x-1)`

Combine like terms on the left:

`3x-x+2=4(2x-1)\\2x+2=4(2x-1)`

Distribute out the right:

`2x+2=4(2x-1)\\2x+2=8x-4`

Subtract 2x from both sides. The left side cancels:

`(2x+2)-2x=(8x-4)-2x\\2=6x-4`

Add 4 to both sides. The right side cancels:

`2+4=(6x-4)+4\\6=6x`

Divide each side by 6:

`(6)/6=(6x)/6\\x=1`

Therefore, the solution is: x=1.
