Answer 3

I can help you solve the equation 4x-3(x-7)=2x+15. Here are the steps:

1. Expand the parentheses by multiplying -3 with each term inside: 4x-3x+21=2x+15 2. Simplify by combining like terms on each side: x+21=2x+15 3. Subtract x from both sides: 21=x+15 4. Subtract 15 from both sides: 6=x 5. Check the solution by plugging x=6 into the original equation: 4(6)-3(6-7)=2(6)+15 6. Simplify both sides and verify that they are equal: 24-3(1)=12+15 7. 24-3=12+15 8. 21=21

Therefore, the solution is x=6. You can also use online calculators to solve equations, such as [Symbolab](https://ru.symbolab.com/solver/equation-calculator) or [Mathway](https://www.mathway.com/ru/Algebra).
