Answer 3

1) 8x + 10 = 3x - 10 To solve for x, first combine like terms: 8x - 3x = -10 - 10 5x = -20 Then, divide both sides by 5 to isolate x: x = -4

2) 10(y - 2) - 12 = 14(y - 2) + 3 First, distribute the numbers outside the parentheses: 10y - 20 - 12 = 14y - 28 + 3 Combine like terms: 10y - 32 = 14y - 25 Subtract 10y from both sides: -32 = 4y - 25 Add 25 to both sides: -7 = 4y Finally, divide both sides by 4: y = -7/4 or -1.75

3) -25(-8x + 6) = -750 First, distribute the -25: 200x - 150 = -750 Add 150 to both sides: 200x = -600 Finally, divide both sides by 200: x = -3

4) -10(-4y + 10) = -300 First, distribute the -10: 40y - 100 = -300 Add 100 to both sides: 40y = -200 Finally, divide both sides by 40: y = -5

5) -10x + 128 = -74x + 6 First, add 74x to both sides and subtract 128 from both sides: 64x = -122 Finally, divide both sides by 64: x = -61/32 or -1.90625

6) 3(5y - 6) = 16y - 8 First, distribute the 3: 15y - 18 = 16y - 8 Subtract 15y from both sides: -18 = y - 8 Add 8 to both sides: -10 = y So, y = -10

7) -5(x + 1) - 11 = -1 First, distribute the -5: -5x - 5 - 11 = -1 Combine like terms: -5x - 16 = -1 Add 16 to both sides: -5x = 15 Finally, divide both sides by -5: x = -3

8) -8y + 4 = -2(5y + 6) First, distribute the -2: -8y + 4 = -10y - 12 Add 10y to both sides: 2y + 4 = -12 Subtract 4 from both sides: 2y = -16 Finally, divide both sides by 2: y = -8

9) 20 + 30x = 20 + x First, subtract 20 from both sides: 30x = x Then, subtract x from both sides: 29x = 0 Finally, divide both sides by 29: x = 0

10) 26 - 5y = 2 - 9y First, add 9y to both sides and subtract 26 from both sides: 4y = -24 Finally, divide both sides by 4: y = -6

These are the solutions to the given equations.
