Question

|5х+7| - 10,3 = -4,3Решите ​

Answer 1

|5х+7|-10,3=-4,3
|5х+7|=-4,3+10,3
|5х+7|=6
5х+7=6
5х=6-7
5х=-1
Х=-1:5
Х=-0,2

Answer 2

To solve the equation |5x + 7| - 10.3 = -4.3, follow these steps:

Step 1: Get rid of the constant terms on the left side of the equation by adding 10.3 to both sides:

|5x + 7| = -4.3 + 10.3 |5x + 7| = 6

Step 2: Now, split the equation into two separate equations without the absolute value:

1. 5x + 7 = 6
2. 5x + 7 = -6

Step 3: Solve each equation for x:

1. 5x + 7 = 6 Subtract 7 from both sides: 5x = 6 - 7 5x = -1 Divide by 5: x = -1/5

2. 5x + 7 = -6 Subtract 7 from both sides: 5x = -6 - 7 5x = -13 Divide by 5: x = -13/5

Step 4: The solutions to the original equation are x = -1/5 and x = -13/5.
