Solution to the Given Equations

1) (128 + 49) - X = 28 2) X - (133 + 75) = 32 3) 145 - (x + 45) = 50 4) (39 + x) - 27 = 22 5) 500 – (120 – x) = 479 - 99 6) 220 + (x - 120) = 997 - 736

Let's solve these equations step by step.

1) (128 + 49) - X = 28 - First, solve the parentheses: 128 + 49 = 177 - Then, subtract X from 177: 177 - X = 28 - Now, solve for X: X = 177 - 28 = 149

2) X - (133 + 75) = 32 - First, solve the parentheses: 133 + 75 = 208 - Then, subtract 208 from X: X - 208 = 32 - Now, solve for X: X = 32 + 208 = 240

3) 145 - (x + 45) = 50 - First, solve the parentheses: x + 45 - Then, subtract the result from 145: 145 - (x + 45) = 50 - Now, solve for x: x + 45 = 145 - 50 = 95 - x = 95 - 45 = 50

4) (39 + x) - 27 = 22 - First, solve the parentheses: 39 + x = 39 + x - Then, subtract 27 from the result: 39 + x - 27 = 22 - Now, solve for x: 39 + x - 27 = 22 - x + 12 = 22 - x = 22 - 12 = 10

5) 500 – (120 – x) = 479 - 99 - First, solve the parentheses: 120 - x = 120 - x - Then, subtract the result from 500: 500 - (120 - x) = 479 - 99 - Now, solve for x: 500 - 120 + x = 479 - 99 - 380 + x = 380 - x = 380 - 380 = 0

6) 220 + (x - 120) = 997 - 736 - First, solve the parentheses: x - 120 = x - 120 - Then, add the result to 220: 220 + (x - 120) = 997 - 736 - Now, solve for x: 220 + x - 120 = 261 - x + 100 = 261 - x = 261 - 100 = 161

So, the solutions to the given equations are: 1) X = 149 2) X = 240 3) x = 50 4) x = 10 5) x = 0 6) x = 161
