Answer 3

It looks like you've provided a system of three equations with variables. Let's solve this system step by step:

Equation 1: (-4 + 2x) * 6 = 16 + 2x

Distribute and solve for x: -24 + 12x = 16 + 2x Subtract 2x from both sides: 10x - 24 = 16 Add 24 to both sides: 10x = 40 Divide both sides by 10: x = 4

Equation 2: 7x - 9 - 2(4 + 2x) = 16

Distribute and solve for x: 7x - 9 - 8 - 4x = 16 Combine like terms: 3x - 17 = 16 Add 17 to both sides: 3x = 33 Divide both sides by 3: x = 11

Equation 3: 1.2(14 - 10x) + 6(2 - 0.4x) = 0

Distribute and solve for x: 16.8 - 12x + 12 - 2.4x = 0 Combine like terms: -14.4x + 28.8 = 0 Subtract 28.8 from both sides: -14.4x = -28.8 Divide both sides by -14.4: x = 2

So, the solutions for the system of equations are x = 4, x = 11, and x = 2.
