Question

32*х-59=453 у:23+312=390 7035:(120-х)=67

Answer 1

32*х-59=453
32*х=453+59
32*х=512
х=16


2) у:23+312=390
1/23у+312=390 |*23
у+7176=8970
у=8970-7176
у= 1794.



3)7035:(120-х)=67
7035/120-х=67 |÷67
105=120-х
х=120-105
х=15

Answer 2

To solve each of these equations, we'll follow the standard steps for solving linear equations. Let's tackle them one by one:

1. 32*x - 59 = 453

Step 1: Add 59 to both sides to isolate the term with 'x': 32x = 453 + 59 32x = 512

Step 2: Divide both sides by 32 to solve for 'x': x = 512 / 32 x = 16

So, the solution for this equation is x = 16.

2. у/23 + 312 = 390

Step 1: Subtract 312 from both sides to isolate the term with 'у': у/23 = 390 - 312 у/23 = 78

Step 2: Multiply both sides by 23 to solve for 'у': у = 78 * 23 у = 1794

So, the solution for this equation is у = 1794.

3. 7035/(120 - х) = 67

Step 1: Multiply both sides by (120 - х) to isolate the fraction: 7035 = 67 * (120 - х)

Step 2: Divide both sides by 67 to solve for (120 - х): (120 - х) = 7035 / 67 (120 - х) = 105

Step 3: Subtract 105 from both sides to solve for 'х': 120 - х = 105

Step 4: Subtract 105 from both sides to isolate 'х': х = 120 - 105 х = 15

So, the solution for this equation is х = 15.

To summarize:

1. x = 16
2. у = 1794
3. х = 15
