Answer 1

Răspuns:

Explicație pas cu pas:

37/3:{[9/4(5/3+15x/8)]·8/11+5/3}=5

37/15=[45/4(8+9x)/24]·8/11+5/3

37/15=45(8+9x)/3×4×11+5/3

37/5=45(8+9x)/44+5

37/5-5=45(8+9x)/44

12/5=45(8+9x)/44

4/5=15(8+9x)/44   ⇒176=75(8+9x)        176-75·8=75·9x

176-600=675x      -424=675x        x=-424/675=-0,62(814)
