№1 (х-14,2)+13,2=18,127; №2 (х+14,013):14,2=1,87; №3 16,2:(4х+1,75)=0,02; №4 (2х-18)*14,2=147,112.​

Answer 1

Ответ:

Пошаговое объяснение:

№1 (х-14,2)+13,2=18,127;

х=18.127-13.2+14.2

х=19.127

№2 (х+14,013):14,2=1,87;

х+14.013=1.87*14.2

х+14.013=26.554

х=26.554-14.013

х=12.541

№3 16,2:(4х+1,75)=0,02;

4х+1.75=16.2:0.02

4х+1.75=810

4х=810-1.75

4х=808.25

х=808.25:4

х=202.0625

№4 (2х-18)*14,2=147,112.​

2х-18=147.112:14.2

2х-18=10.36

2х=10.36+18

2х=28.36

х=28.36:2

х=14.18

Answer 2

Sure, I can help you solve these equations! Here are the solutions to each of the equations:

1. (х-14,2)+13,2=18,127

• First, we can simplify the left side of the equation by combining like terms: х - 14,2 + 13,2 = х - 1
• Now we can rewrite the equation as: х - 1 = 18,127
• To solve for х, we can add 1 to both sides of the equation: х = 19,127

Therefore, the solution to the equation is х = 19,127.

2. (х+14,013):14,2=1,87

• To solve for х, we can multiply both sides of the equation by 14,2: х + 14,013 = 1,87 * 14,2
• We can simplify the right side of the equation by multiplying: х + 14,013 = 26,654
• Then we can subtract 14,013 from both sides of the equation: х = 12,641

Therefore, the solution to the equation is х = 12,641.

3. 16,2:(4х+1,75)=0,02

• To solve for х, we can start by multiplying both sides of the equation by (4х + 1,75): 16,2 = 0,02 * (4х + 1,75)
• We can simplify the right side of the equation by multiplying: 16,2 = 0,08х + 0,035
• Then we can subtract 0,035 from both sides of the equation: 16,165 = 0,08х
• Finally, we can divide both sides of the equation by 0,08: х = 202,06

Therefore, the solution to the equation is х = 202,06.

4. (2х-18)*14,2=147,112

• To solve for х, we can start by multiplying the terms on the left side of the equation: 28,4х - 255,6 = 147,112
• Then we can add 255,6 to both sides of the equation: 28,4х = 402,712
• Finally, we can divide both sides of the equation by 28,4: х = 14,18

Therefore, the solution to the equation is х = 14,18.
