Answer 1

30x + x + 7x = 7866
Combine like terms: 38x = 7866
Solve for x: x = 7866 / 38
x = 207
6m + m - 35 = 21
Combine like terms: 7m - 35 = 21
Add 35 to both sides: 7m = 21 + 35
7m = 56
Solve for m: m = 56 / 7
m = 8
6a + 3a - a = 6400
Combine like terms: 8a = 6400
Solve for a: a = 6400 / 8
a = 800
5n + 9n + 32 = 200
Combine like terms: 14n + 32 = 200
Subtract 32 from both sides: 14n = 200 - 32
14n = 168
Solve for n: n = 168 / 14
n = 12
(x + 9) * 4 = 76
Distribute the 4: 4x + 36 = 76
Subtract 36 from both sides: 4x = 76 - 36
4x = 40
Solve for x: x = 40 / 4
x = 10
102m - 4m + 8 = 1968
Combine like terms: 98m + 8 = 1968
Subtract 8 from both sides: 98m = 1968 - 8
98m = 1960
Solve for m: m = 1960 / 98
m = 20
(3x + 5x) * 18 = 144
Combine like terms: 8x * 18 = 144
Multiply: 144x = 144
Solve for x: x = 144 / 144
x = 1
4^x * 8/3 = 48096
To solve for x, we can rewrite this as: 4^x = 48096 * 3/8
4^x = 18036
x = log(18036) / log(4) (using logarithms)
x ≈ 5.5
7(15y - 7y) = 224
Combine like terms inside the parentheses: 7(8y) = 224
56y = 224
Solve for y: y = 224 / 56
y = 4
35(14 + x) - 476 + 6x = 383
Distribute the 35: 490 + 35x - 476 + 6x = 383
Combine like terms: 41x + 14 = 383 + 476
41x + 14 = 859
Subtract 14 from both sides: 41x = 859 - 14
41x = 845
Solve for x: x = 845 / 41
x ≈ 20.61
3(2x + 5) + (3x + 9) * 2 + (5x - 4) * 4 = 6577
Let's simplify this equation step by step:
6x + 15 + 6x + 18 + 20x - 16 = 6577
Combine like terms: 32x + 17 = 6577
Subtract 17 from both sides: 32x = 6577 - 17
32x = 6560
Solve for x: x = 6560 / 32
x = 205
144 + (3y - 18) * 5 + 4y = 149
Let's simplify this equation step by step:
144 + 15y - 90 + 4y = 149
Combine like terms: 19y + 54 = 149
Subtract 54 from both sides: 19y = 149 - 54
19y = 95
Solve for y: y = 95 / 19
y = 5
