Question

What is the value of x in the equation 2(x+3)=4(x-1)

Answer 1

Firstly, expand the equation.

`2(x + 3) = 4(x - 1) \\ 2x + 6 = 4x - 4`

Next, move the variable x to the left and all the constant to the right.

`2x + 6 = 4x - 4 \\ 2x - 4x = - 4 - 6 \\ - 2x = - 10`

Then, solve for x.

`- 2x = - 10 \\ x = ( - 10)/( - 2) \\ x = 5`
