Solving Equations with an Unknown Addend

To solve equations with an unknown addend, we need to isolate the variable on one side of the equation. Let's solve the given equations step by step:

1. 28 – 5x = 18: To isolate the variable, we can subtract 28 from both sides of the equation: 28 - 28 - 5x = 18 - 28 -5x = -10 Now, divide both sides of the equation by -5 to solve for x: -5x / -5 = -10 / -5 x = 2

2. 6x + 40 = 64: To isolate the variable, we can subtract 40 from both sides of the equation: 6x + 40 - 40 = 64 - 40 6x = 24 Now, divide both sides of the equation by 6 to solve for x: 6x / 6 = 24 / 6 x = 4

3. 36 - 2x = 24: To isolate the variable, we can subtract 36 from both sides of the equation: 36 - 36 - 2x = 24 - 36 -2x = -12 Now, divide both sides of the equation by -2 to solve for x: -2x / -2 = -12 / -2 x = 6

4. 45 - x = 36: To isolate the variable, we can subtract 45 from both sides of the equation: 45 - 45 - x = 36 - 45 -x = -9 Now, multiply both sides of the equation by -1 to solve for x: -1 * -x = -1 * -9 x = 9

5. 88 - 7x = 11: To isolate the variable, we can subtract 88 from both sides of the equation: 88 - 88 - 7x = 11 - 88 -7x = -77 Now, divide both sides of the equation by -7 to solve for x: -7x / -7 = -77 / -7 x = 11

6. 34 + 8x = 106: To isolate the variable, we can subtract 34 from both sides of the equation: 34 - 34 + 8x = 106 - 34 8x = 72 Now, divide both sides of the equation by 8 to solve for x: 8x / 8 = 72 / 8 x = 9

Therefore, the solutions for the given equations are: x = 2, 4, 6, 9, 11, 9.
