Question

| 5x+6 | = 3.Алгебра, 7 класс.​

Answer 1

5x+6=3

5x=-3

X=-0.6

5x+6=-3

5x=-9

X=-1.8

Answer 2

To solve the equation |5x+6| = 3, we need to consider two cases: when the expression inside the absolute value is positive and when it is negative.

Case 1: 5x+6 > 0 In this case, we can remove the absolute value bars without changing the equation: 5x + 6 = 3

Now, we can solve this equation for x: 5x = 3 - 6 5x = -3 x = -3/5

Case 2: 5x+6 < 0 In this case, we need to change the sign of the expression inside the absolute value and solve the equation: -(5x + 6) = 3

Now, we can simplify and solve for x: -5x - 6 = 3 -5x = 3 + 6 -5x = 9 x = 9/-5 x = -9/5

So, the solutions to the equation |5x+6| = 3 are x = -3/5 and x = -9/5.
