1)-3y-9y+5y=2,1 2)-2,4m+3,8+1,2=-0,052

Answer 1

....................................

Answer 2

Let's solve each of the equations step by step:

1. -3y - 9y + 5y = 2.1

First, combine like terms on the left-hand side:

-3y - 9y + 5y = -7y

Now, the equation becomes:

-7y = 2.1

To solve for y, divide both sides of the equation by -7:

y = 2.1 / -7 y = -0.3

So, the solution for this equation is y = -0.3.

2. -2.4m + 3.8 + 1.2 = -0.052

First, combine the constants on the left-hand side:

3.8 + 1.2 = 5

Now, the equation becomes:

-2.4m + 5 = -0.052

Next, move 5 to the right-hand side by subtracting it from both sides:

-2.4m = -0.052 - 5 -2.4m = -5.052

Finally, to solve for m, divide both sides of the equation by -2.4:

m = -5.052 / -2.4 m ≈ 2.105

So, the solution for this equation is m ≈ 2.105.
