Answer 2

To solve the equation 6(x+2) + 3(3x+7) = 4(5+4x) - 7, you'll need to simplify it step by step and solve for the variable x. Here's how you can do it:

1. Distribute the constants and variables inside the parentheses: 6x + 12 + 9x + 21 = 20 + 16x - 7

2. Combine like terms on both sides of the equation: (6x + 9x) + (12 + 21) = 20 + 16x - 7 15x + 33 = 20 + 16x - 7

3. Move the 16x term from the right side to the left side by subtracting 16x from both sides: 15x - 16x + 33 = 20 - 7

4. Simplify both sides further: -x + 33 = 13

5. Now, isolate the variable x by moving the constant term 33 to the other side by subtracting 33 from both sides: -x + 33 - 33 = 13 - 33

6. Simplify: -x = -20

7. Finally, solve for x by multiplying both sides by -1 to make x positive: -1(-x) = -1(-20) x = 20

So, the solution to the equation is x = 20.
