Question

120 + х ∙ 3 = 376 4 ∙ (х – 97) = 68 27401 : х – 119 =398 2400 : (317 + х) = 3 15 ∙ х + 80 = 125

Answer 1

120+3x=376
3x=376-120
3x=256:3
x=85 1/3
4*(x-97)=68
4x-388=68
4x=68+388
4x=456:4
x=114
2400:(317+x)=3
317+x=2400:3
317+x=800
x=800-317
x=483
15x+80=125
15x=125-80
15x=45:15
x=3

Answer 2

Let's solve each equation step by step:

1. 120 + х ∙ 3 = 376

Subtract 120 from both sides:

х * 3 = 256

Divide both sides by 3:

х = 85.33

So the solution is x = 85.33

2. 4 ∙ (х – 97) = 68

Distribute the 4:

4x - 388 = 68

Add 388 to both sides:

4x = 456

Divide both sides by 4:

x = 114

So the solution is x = 114

3. 27401 : х – 119 = 398

Add 119 to both sides:

27401 / x = 517

Divide both sides by 517:

x = 53

So the solution is x = 53

4. 2400 : (317 + х) = 3

Multiply both sides by (317 + x):

2400 = 3(317 + x)

Simplify:

2400 = 951 + 3x

Subtract 951 from both sides:

1449 = 3x

Divide both sides by 3:

x = 483

So the solution is x = 483

5. 15 ∙ х + 80 = 125

Subtract 80 from both sides:

15x = 45

Divide both sides by 15:

x = 3

So the solution is x = 3.

Therefore, the solutions to the equations are:

x = 85.33, 114, 53, 483, and 3.
