Question

X+6,7:4=2,5 (x-4,6):4=2,6 21,6:х+1,4=3,6

Answer 1

1)х+6,7:4=2,5
х+6,7=2,5×4
х+6,7=10
х=10-6,7
х=3,3

2)(х-4,6):4=2,6
х-4,6=2,6×4
х-4,6=10,4
х=10,4+4,6
х=15

3)21,6:х+1,4=3,6
21,6:х=3,6-1,4
21,6:х=2,2
х=21,6:2,2
х= 18

Answer 3

It looks like you've provided a set of equations with variables. Let's solve them step by step:

1. x + 6.7:4 = 2.5 To solve for x, you can start by isolating x: x + 6.7 = 2.5 * 4 x + 6.7 = 10 x = 10 - 6.7 x ≈ 3.3

2. (x - 4.6):4 = 2.6 To solve for x in this equation, you can isolate x: (x - 4.6) = 2.6 * 4 x - 4.6 = 10.4 x = 10.4 + 4.6 x = 15

3. 21.6:x + 1.4 = 3.6 To solve for x in this equation, you can isolate x: 21.6/x + 1.4 = 3.6 21.6/x = 3.6 - 1.4 21.6/x = 2.2

Now, to find x, you can invert the fraction on the left side of the equation: x/21.6 = 1/2.2

To solve for x, multiply both sides by 21.6: x = 21.6 / 2.2 x ≈ 9.818 (rounded to three decimal places)

So, the solutions to the equations are approximately:

1. x ≈ 3.3
2. x = 15
3. x ≈ 9.818
