Question

1)2,3+x=-5,32)y-4,9=2,93)-1,2y=0,6

Answer 1

Ответ:

1) 2,3+x=-5,3

x = -5.3-2.3

x =-7.6

2) y-4.9=2.9

y = 2.9+4.9

y = 7.8

3)-1.2y=0.6

y = 0.6/-1.2

y = -0.5

Answer 2

To solve these equations, I'll go through each one step by step:

1. 2 + 3x = -5

Step 1: Move the constant term to the other side by subtracting 2 from both sides: 2 + 3x - 2 = -5 - 2 3x = -7

Step 2: Isolate x by dividing both sides by 3: 3x / 3 = -7 / 3 x = -7/3

So the solution for the first equation is x = -7/3.

2. y - 4.9 = 2.93

Step 1: Move the constant term to the other side by adding 4.9 to both sides: y - 4.9 + 4.9 = 2.93 + 4.9 y = 7.83

So the solution for the second equation is y = 7.83.

3. -1.2y = 0.6

Step 1: Isolate y by dividing both sides by -1.2: (-1.2y) / (-1.2) = 0.6 / (-1.2) y = -0.5

So the solution for the third equation is y = -0.5.

To summarize:

1. x = -7/3
2. y = 7.83
3. y = -0.5
