Question

0.3x+7.3=-1 2/3 x+1.4

Answer 1

0,3х+1 2/3х=1,4-7,3
3/10х-5/3х=-5,9
9/30х-50/30х=-59/10
-41/30х=-59/10
Х=-59/10:(-41/30)=-59/10*(-30/41)
Х=177/41=4 13/41

Answer 3

To solve the equation $0.3x + 7.3 = -\frac{1}{3}x + 1.4$, you want to isolate the variable $x$ on one side of the equation. Here's how you can do it step by step:

1. Combine like terms: First, let's combine the $x$ terms on one side and the constant terms on the other side.

   $0.3x + \frac{1}{3}x = 1.4 - 7.3$

   $\frac{3}{10}x + \frac{1}{3}x = -5.9$

2. Get a common denominator: To combine the fractions, find a common denominator, which in this case is 30.

   $\frac{9}{30}x + \frac{10}{30}x = -5.9$

3. Combine the fractions:

   $\frac{19}{30}x = -5.9$

4. Isolate $x$:

   $x = \frac{-5.9}{\frac{19}{30}}$

   To divide by a fraction, multiply by its reciprocal:

   $x = -5.9 \times \frac{30}{19}$

   $x \approx -9.21$

So the solution to the equation $0.3x + 7.3 = -\frac{1}{3}x + 1.4$ is approximately $x \approx -9.21$.
