Question

1. Aflati valoarea necunoscutei m:
[(m+428:4)x2+5]x2-186=1000:2+6x50​

Answer 1

Răspuns:

Explicație pas cu pas:

[(m+428:4)x2+5]x2-186=1000:2+6x50

[(m+107)x2+5]x2-186=500+300

[(m+107)x2+5]x2-186=800

[(m+107)x2+5]x2 = 186 + 800 = 986

(m+107)x2+5 = 986 : 2 = 493

(m+107)x2 = 493 - 5 = 488

m + 107 = 488 : 2 = 244

m = 244 - 107 = 137

Answer 2

Răspuns:

[(m+428:4)x2+5]x2-186=1000:2+6x50

[(m+107)x2+5]x2-186=500+300

[(m+107)x2+5]x2-186=800

[(m+107)x2+5]x2 = 800+186

[(m+107)x2+5]x2 = 986

[(m+107)x2+5] = 986:2

[(m+107)x2+5] = 493

[(m+107)x2 = 493-5

[(m+107)x2 = 488

m+107 = 488 : 2

m +107 = 244

m = 244 - 107

m = 137
