Question

(10х+6)=4 (3х-9)=6 (2,4х+1,2)=6

Answer 1

Ответ:

Пошаговое объяснение:

(10х+6)=4

10x = -2

x = -0,2

(3х-9)=6

3x = 15

x = 5

(2,4х+1,2)=6

2,4x = 4,8

x = 4

Answer 2

$(10x + 6) = 4 \\ 10x = 4 - 6 \\ 10x = - 2 \\ x = - \frac{1}{5}$
номер 1.
$(3x - 9) = 6 \\ 3x = 6 + 9 \\ 3x = 15 \\ x = 5$
номер 2.
$(2.4x + 1.2) = 6 \\ 2.4x = 6 - 1.2 \\ 2.4x = 4.8 \\ x = 2$
номер 3.

Answer 3

To solve the given equations, we'll start by solving each equation individually:

1. 10x + 6 = 4: Subtract 6 from both sides to isolate the variable: 10x = 4 - 6 10x = -2 Divide both sides by 10: x = -2/10 Simplify: x = -1/5

2. 3x - 9 = 6: Add 9 to both sides to isolate the variable: 3x = 6 + 9 3x = 15 Divide both sides by 3: x = 15/3 Simplify: x = 5

3. 2.4x + 1.2 = 6: Subtract 1.2 from both sides to isolate the variable: 2.4x = 6 - 1.2 2.4x = 4.8 Divide both sides by 2.4: x = 4.8/2.4 Simplify: x = 2

Therefore, the solutions for the given equations are: x = -1/5, 5, and 2.
