Answer 2

It looks like you have a system of two equations with two variables, x and h. Let's solve it step by step.

1. The first equation is: 3x + 12x - 3 = 3

   Combine like terms: 15x - 3 = 3

   Add 3 to both sides: 15x = 6

   Now, divide both sides by 15 to solve for x: x = 6 / 15 x = 2/5

2. The second equation is: 7x/5 - (x + 6) = 6(x - 1)

   Distribute the 6 on the right side: 7x/5 - x - 6 = 6x - 6

   Subtract 7x/5 from both sides: -x - 6 = 6x - 6 - 7x/5

   Combine like terms on the right side: -x - 6 = -x/5

   Now, add x to both sides to isolate the constant term on the right side: -6 = -x/5 + x

   To eliminate the fractions, multiply both sides by 5: -30 = -x + 5x

   Combine like terms on the right side: -30 = 4x

   Now, divide both sides by 4 to solve for x: x = -30 / 4 x = -15/2

So, the solution to the system of equations is: x = 2/5 h = -15/2
