Problem 1 :
2x + 3 = 16 - (2x - 3)
Problem 2 :
5(x - 3) - 7(6 - x) = 24 - 3(8 - x) - 3
Problem 3 :
8(x - 1) + 17(x - 3) = 4(4x - 9) + 4
Problem 4 :
15(x - 1) + 4(x + 3) = 2(7 + x)
Problem 5 :
5x - (4x - 7)(3x - 5) = 6 - 3(4x - 9)(x - 1)
Problem 6 :
Problem 7 :
5x - 6(x - 5) = 2(x + 5) + 5(x - 4)
Problem 8 :
Problem 9 :
Problem 10 :
1. Answer :
2x + 3 = 16 - (2x - 3)
2x + 3 = 16 - 2x + 3
2x + 3 = -2x + 19
4x + 3 = 19
4x = 16
x = 4
2. Answer :
5(x - 3) - 7(6 - x) = 24 - 3(8 - x) - 3
5x - 15 - 42 + 7x = 24 - 24 + 3x - 3
12x - 57 = 3x - 3
9x - 57 = -3
9x = 54
x = 6
3. Answer :
8(x - 1) + 17(x - 3) = 4(4x - 9) + 4
8x - 8 + 17x - 51 = 16x - 36 + 4
25x - 59 = 16x - 32
9x - 59 = -32
9x = 27
x = 3
4. Answer :
15(x - 1) + 4(x + 3) = 2(7 + x)
15x - 15 + 4x + 12 = 14 + 2x
19x - 3 = 14 + 2x
17x - 3 = 14
17x = 17
x = 1
5. Answer :
5x - (4x - 7)(3x - 5) = 6 - 3(4x - 9)(x - 1)
5x - (12x2- 20x - 21x + 35) = 6 - 3(4x2- 4x - 9x + 9)
5x - (12x2- 41x + 35) = 6 - 3(4x2- 13x + 9)
5x - 12x2 + 41x - 35 = 6 - 12x2 + 39x - 27
-12x2 + 46x - 35 = -12x2 + 39x - 21
46x - 35 = 39x - 21
7x - 35 = -21
7x = 14
x = 2
6. Answer :
Least common multiple of the denominators 4 and 5 is 20. Multiply both sides of the equation by 20 to get rid of the denominators and solve for x..
16x - 35 = 4x + 5x
16x - 35 = 9x
7x - 35 = 0
7x = 35
x = 5
7. Answer :
5x - 6(x - 5) = 2(x + 5) + 5(x - 4)
5x - 6x + 30 = 2x + 10 + 5x - 20
-x + 30 = 7x - 10
-8x + 30 = -10
-8x = -40
x = 5
8. Answer :
9(x - 2) + 2(x + 10) = 90
9x - 18 + 2x + 20 = 90
11x + 2 = 90
11x = 88
x = 8
9. Answer :
52(x + 2) = 455 + 5(5x)
52x + 104 = 455 + 25x
27x + 104 = 455
27x = 351
x = 13
10. Answer :
6(x + 35) - 4(x + 7) = 9(x + 21)
6x + 210 - 4x - 28 = 9x + 189
2x + 182 = 9x + 189
-7x + 182 = 189
-7x = 7
x = -1
