Answer 2

Ответ:

Пошаговое объяснение:3х+5х=8х

8*х+96=1568

8*х=1568-96

8*х=1472

х=1472:8

х=184

Answer 3

To solve each of these equations, we need to find the value of the variable (Х or у or а) that satisfies the equation. Let's go through each equation step by step:

1. 3Х + 5Х + 96 = 1568 Combine the like terms on the left side of the equation: 8Х + 96 = 1568 Now, isolate Х by moving 96 to the right side of the equation: 8Х = 1568 - 96 8Х = 1472 Finally, solve for Х: Х = 1472 / 8 Х = 184

So, Х = 184 is the solution to the first equation.

2. 357у - 149у - 1843 = 11469 Combine the like terms on the left side of the equation: (357у - 149у) - 1843 = 11469 208у - 1843 = 11469 Now, isolate у by moving -1843 to the right side of the equation: 208у = 11469 + 1843 208у = 13312 Finally, solve for у: у = 13312 / 208 у = 64

So, у = 64 is the solution to the second equation.

3. 88880 ÷ 110 + Х = 809 First, perform the division on the left side of the equation: 808 + Х = 809 Now, isolate Х by moving 808 to the right side of the equation: Х = 809 - 808 Х = 1

So, Х = 1 is the solution to the third equation.

4. 6871 + а ÷ 121 = 7000 Isolate а by moving 6871 to the right side of the equation: а ÷ 121 = 7000 - 6871 а ÷ 121 = 129 Finally, solve for а: а = 129 * 121 а = 15579

So, а = 15579 is the solution to the fourth equation.

To summarize:

1. Х = 184
2. у = 64
3. Х = 1
4. а = 15579
