Question

0,4(x-9=0.7+0.3(x+2)

Answer 1

Ответ:

49

Пошаговое объяснение:

0,4(x-9)=0.7+0.3(x+2)

0,4х-3,6=0,7+0,3х+0,6

0,4х-3,6=1,3+0,3х

0,4х-0,3х=1,3+3,6

0,1х=4,9

х=4,9:0,1

х=49

Answer 2

Ответ: 0,4*x-3,6=0,7+0,3*x+0,6⇒0,1*x=0,7+0,6+3,6=4,9⇒x=49.

Answer 3

It seems like there might be a typo or a formatting issue in the equation you provided. Let me correct it and solve for $x$:

Original equation: $0.4(x-9) = 0.7 + 0.3(x+2)$

First, distribute the constants:

$0.4x - 3.6 = 0.7 + 0.3x + 0.6$

Combine like terms:

$0.4x - 0.3x = 0.7 + 0.6 + 3.6$

Simplify further:

$0.1x = 4.9$

Now, solve for $x$:

$x = \frac{4.9}{0.1} = 49$

So, the solution for the equation is $x = 49$.

Answer 4

Let's solve the equation step by step:

$0.4(x-9) = 0.7 + 0.3(x+2)$

1. Distribute the constants outside the parentheses:

$0.4x - 3.6 = 0.7 + 0.3x + 0.6$

2. Combine like terms:

$0.4x - 0.3x = 0.7 + 0.6 + 3.6$

$0.1x = 4.9$

3. Divide by 0.1 to solve for $x$:

$x = \frac{4.9}{0.1}$

$x = 49$

Therefore, the solution to the equation is $x = 49$.
