Question

O literă, vă rog! Mulțumesc mult !!!

Answer 1

Răspuns:

a) 3/4·[5·(2/3 - ³⁾x) + 3/2] = 7x/2

3/4·[²⁾5·(2 - 3x)/3 + ³⁾3/2] = 7x/2

3/4·[10(2 - 3x) + 9]/6 = 7x/2

3/4·(20 - 30x + 9)/6 = 7x/2

3(29 - 30x)/24 = 7x/2

6(29 - 30x) = 56x

174 - 180x = 168x

174 = 168x + 180x

348x = 174

x = 348/174

x = 1/2
