Question

(z + 12,6) : 3/5 =86 Найдите z

Answer 1

z+12,6=86*3/5
z+12,6=51,6
z=51,6-12,6
z=39

Answer 2

To solve for z in the equation:

(z + 12.6) / 3/5 = 86

We can simplify by multiplying both sides by the reciprocal of 3/5:

(z + 12.6) / 3/5 = 86

(z + 12.6) * 5/3 = 86

Multiplying both sides by 3/5 gives:

(z + 12.6) * 5/3 * 3/5 = 86 * 3/5

(z + 12.6) = 51.6

Subtracting 12.6 from both sides gives:

z = 39.
