Answer 2

To solve the equation 15у - 8 = -6у + 4.6, we can start by simplifying the equation by combining like terms:

15у - 8 = -6у + 4.6

Next, let's move all the terms with у to one side of the equation by adding 6у to both sides:

15у + 6у - 8 = 4.6

Combining the terms with у:

21у - 8 = 4.6

Now, let's isolate у by moving the constant term (-8) to the other side of the equation by adding 8 to both sides:

21у - 8 + 8 = 4.6 + 8

Simplifying:

21у = 12.6

Finally, to solve for у, we divide both sides of the equation by 21:

(21у)/21 = 12.6/21

Simplifying:

у = 0.6

Therefore, the solution to the equation 15у - 8 = -6у + 4.6 is у = 0.6.

Moving on to the second equation: -167 + 1.7 = 27 - 1.

Let's solve it step by step:

-167 + 1.7 = 27 - 1

Simplifying:

-165.3 = 26

Therefore, the equation -167 + 1.7 = 27 - 1 is not true since -165.3 is not equal to 26.
