Question

-4,6z+5,2z+(-0,8)z=5,7

Answer 1

Ответ:

-28,5

Решение:

-4,6z+5,2z+(-0,8)z=5,7

0,6z-0,8z=5,7

-0,2z=5,7

z=-28,5

Answer 2

решение:                                                          

-4,6z+5,2z+(-0,8)z=5,7

0,6z-0,8z=5,7

-0,2z=5,7

Answer 3

To solve the equation -4,6z + 5,2z + (-0,8)z = 5,7, we can combine like terms on the left-hand side of the equation:

(-4,6 + 5,2 - 0,8)z = 5,7

Now, we simplify the left-hand side:

(-0,2)z = 5,7

To isolate z, we divide both sides of the equation by -0,2:

z = 5,7 / (-0,2)

Performing the division, we get:

z = -28,5

Therefore, the solution to the equation is z = -28,5.
