Question

А)(4,6х + 5,8) : 1,6 = 6,5 б)4,2х + 8,4 = 14,7

Answer 1

4,6х+5,8=10,4
4,6х=10,4-5,8
4,6х=4,6
х=1

4,2х=14,7-8,4
4,2х=6,3
х=1,5

Answer 2

a) To solve the equation (4,6х + 5,8) : 1,6 = 6,5, we can use the following steps:

1. Multiply both sides of the equation by 1.6 to eliminate the division: (4,6х + 5,8) = 1.6 * 6,5

2. Simplify the right-hand side of the equation: (4,6х + 5,8) = 10.4

3. Subtract 5.8 from both sides of the equation to isolate the variable: 4,6х = 4.6

4. Finally, divide both sides of the equation by 4.6: х = 1

Therefore, the solution to the equation (4,6х + 5,8) : 1,6 = 6,5 is х = 1.

b) To solve the equation 4,2х + 8,4 = 14,7, we can use the following steps:

1. Subtract 8.4 from both sides of the equation to isolate the variable term: 4,2х = 6,3

2. Divide both sides of the equation by 4.2 to solve for x: х = 1.5

Therefore, the solution to the equation 4,2х + 8,4 = 14,7 is х = 1.5.
