Question

(163 - х) - 117 = 0 (456 + 112) - x = 400 145 - (х + 45) = 50 x - (203 + 303) = 34 (39 + х) - 27 = 22 468 - 217 - х = 51

Answer 1

163-x-117=0
x=163-117
x=46
456+112-x=400
x=456+112-400
x=168
145-x-45=50
x=145-45-50
x=50
x-203-303=34
x=34+203+303
x=540
39+x-27=22
x=22-39+27
x=10
468-217-x=51
x=468-217-51
x=200

Answer 2

Let's solve each equation step by step:

1. (163 - x) - 117 = 0 Start by simplifying the expression inside the parentheses: 163 - x - 117 = 0 Combine like terms: 46 - x = 0 Add x to both sides: 46 = x

Therefore, the solution to the first equation is x = 46.

2. (456 + 112) - x = 400 Start by simplifying the expression inside the parentheses: 568 - x = 400 Subtract 568 from both sides: -x = 400 - 568 -x = -168 Multiply both sides by -1 to solve for x: x = 168

Therefore, the solution to the second equation is x = 168.

3. 145 - (x + 45) = 50 Start by simplifying the expression inside the parentheses: 145 - x - 45 = 50 Combine like terms: 100 - x = 50 Subtract 100 from both sides: -x = 50 - 100 -x = -50 Multiply both sides by -1 to solve for x: x = 50

Therefore, the solution to the third equation is x = 50.

4. x - (203 + 303) = 34 Start by simplifying the expression inside the parentheses: x - 506 = 34 Add 506 to both sides: x = 34 + 506 x = 540

Therefore, the solution to the fourth equation is x = 540.

5. (39 + x) - 27 = 22 Start by simplifying the expression inside the parentheses: 39 + x - 27 = 22 Combine like terms: 12 + x = 22 Subtract 12 from both sides: x = 22 - 12 x = 10

Therefore, the solution to the fifth equation is x = 10.

6. 468 - 217 - x = 51 Start by combining like terms: 251 - x = 51 Subtract 251 from both sides: -x = 51 - 251 -x = -200 Multiply both sides by -1 to solve for x: x = 200

Therefore, the solution to the sixth equation is x = 200.

To summarize, the solutions to the given equations are:

1. x = 46
2. x = 168
3. x = 50
4. x = 540
5. x = 10
6. x = 200
