Question

3x + 65 = 395 7 (x + 42) = 350 (x - 17): 5 = 29дам 32 бала​

Answer 1

Х + 42 = 350
х = 350 - 42
х = 308
308 + 42 = 350



(х-17) : 5 = 29
х - 17 = 5 • 29
х-17=145
х= 145+17
х= 162
(162-16):5=29



3х+65=395*7
3х+65=2765
3х=2765-65
3х=2700
х= 2700:3
х=900
3*900+65=2765

Answer 2

To solve these equations, we'll start with each one individually:

1. 3x + 65 = 395:

   Subtract 65 from both sides to isolate 3x:

   3x = 395 - 65 3x = 330

   Now, divide both sides by 3 to solve for x:

   x = 330 / 3 x = 110

2. 7(x + 42) = 350:

   First, distribute 7 to both terms inside the parentheses:

   7x + 7 * 42 = 350

   7x + 294 = 350

   Next, subtract 294 from both sides:

   7x = 350 - 294 7x = 56

   Now, divide both sides by 7 to solve for x:

   x = 56 / 7 x = 8

3. (x - 17) / 5 = 29:

   Multiply both sides by 5 to get rid of the fraction:

   x - 17 = 5 * 29 x - 17 = 145

   Add 17 to both sides to isolate x:

   x = 145 + 17 x = 162

So, the solutions to the equations are:

1. x = 110
2. x = 8
3. x = 162
