Answer 1

22х-10-17х=55
5х-10=55
5х=65
х=65:5
х=13
2)40х+15-12=83
40х+3=83
40х=83-3
40х=80
х=2
3)14х+63+3х=114
17х+63=114
17х=114-63
17х=51
х=3
4)12х+39-25=74
12х+14=74
12х=74-14
12х=60
х=5

Answer 2

Solving the Equations

To solve the given equations, let's start by simplifying each equation step by step and then solve for the value of x.

1. Simplify and Solve 2(11x-5)-17x=55: - First, distribute the 2: 22x - 10 - 17x = 55 - Combine like terms: 22x - 17x - 10 = 55 - Simplify: 5x - 10 = 55 - Add 10 to both sides: 5x = 65 - Divide by 5: x = 13 - Therefore, the solution for the first equation is x = 13.

2. Simplify and Solve 5(8x+3)-12=83: - First, distribute the 5: 40x + 15 - 12 = 83 - Combine like terms: 40x + 3 = 83 - Subtract 3 from both sides: 40x = 80 - Divide by 40: x = 2 - Therefore, the solution for the second equation is x = 2.

3. Simplify and Solve 7(2x+9)+3x=114: - First, distribute the 7: 14x + 63 + 3x = 114 - Combine like terms: 17x + 63 = 114 - Subtract 63 from both sides: 17x = 51 - Divide by 17: x = 3 - Therefore, the solution for the third equation is x = 3.

4. Simplify and Solve 3(4x+13)-25=74: - First, distribute the 3: 12x + 39 - 25 = 74 - Combine like terms: 12x + 14 = 74 - Subtract 14 from both sides: 12x = 60 - Divide by 12: x = 5 - Therefore, the solution for the fourth equation is x = 5.

Conclusion

The solutions for the given equations are: - For the first equation: x = 13 - For the second equation: x = 2 - For the third equation: x = 3 - For the fourth equation: x = 5
