12 + 3x = 6x - 4 (x-5)

solve the equation for x

1 answer

To solve the equation for x, we can start by distributing the -4 to the terms inside the parentheses:

12 + 3x = 6x - 4x + 20

Simplifying this gives:

12 + 3x = 2x + 20

Next, we can subtract 2x from both sides to isolate the x terms:

12 + x = 20

Finally, we can subtract 12 from both sides to solve for x:

x = 20 - 12

x = 8

Therefore, the solution to the equation is x = 8.
