Răspuns :
a + b = 43
a : b = 4 rest 3
a = 4b + 3
a ___/____/____/____/+3
b ___/
43 - 3 = 40
40 : 5 = 8
b = 8
a = 4 * 8 + 3
a = 35
a : b = 4 rest 3
a = 4b + 3
a ___/____/____/____/+3
b ___/
43 - 3 = 40
40 : 5 = 8
b = 8
a = 4 * 8 + 3
a = 35
notam primul nr cu x
notam al doilea nr cu 4x+3
4x+3+x=43
5x=43-3
5x=40
x=40:5
x=8(primul nr)
8x4+3=35(al doilea nr)
notam al doilea nr cu 4x+3
4x+3+x=43
5x=43-3
5x=40
x=40:5
x=8(primul nr)
8x4+3=35(al doilea nr)
