Solve for x
4 x-1 / 5 = 2x +1
Answer -1
I got 2/3
(4x-1)/5 =2x+1
5*(4x-1)/5 =2x +1 *5
4x-1 = 10x+5
4x-1 +1 =10x +5+1
4x = 10x+6
4x-10x = 10x+6-10x
-6x = 6
-6x/-6 = 6/-6
x = -1
Ah -- the parenthesis makes a big difference.
(4x-1)/5 =2x+1
4x - 1 = 10x + 5
-6 = 6x
-1 = x
You are right.
Thank you. I was going crazy trying to think what else to do
To solve for x in the equation (4x - 1)/5 = 2x + 1, you need to isolate x on one side of the equation.
Here are the steps to follow:
Step 1: Remove the fraction by multiplying both sides of the equation by 5.
(5) * [(4x - 1)/5] = (5) * (2x + 1)
This simplifies to:
4x - 1 = 10x + 5
Step 2: Move all the terms containing x to one side and the constant terms to the other side of the equation.
4x - 10x = 5 + 1
-6x = 6
Step 3: Divide both sides of the equation by -6 to solve for x.
(-6x)/-6 = 6/-6
This simplifies to:
x = -1
Therefore, the solution to the equation (4x - 1)/5 = 2x + 1 is x = -1.
