Question

1)3х+8х=1,87 2)10х-12=113)3,08:у=4​

Answer 1

1) 11х=1,87
х=0,17
2) 10х=11+12
10х=23
х=2,3
3) у=77/100 (дробь если что)

Answer 2

It looks like you've provided three different algebraic equations. Let's solve each of them:

1. 3x + 8x = 1.87 Combine like terms: 11x = 1.87

Now, to solve for x, divide both sides by 11: x = 1.87/11 ≈ 0.1691

So, the solution to the first equation is approximately x ≈ 0.1691.

2. 10x - 12 = 11 Add 12 to both sides of the equation: 10x = 11 + 12 10x = 23

Now, divide both sides by 10 to solve for x: x = 23/10 = 2.3

The solution to the second equation is x = 2.3.

3. 3.08/y = 4 To solve for y, you can multiply both sides by y to isolate it: 3.08 = 4y

Now, divide both sides by 4 to solve for y: y = 3.08/4 = 0.77

The solution to the third equation is y = 0.77.
