Question

Sa se deteemine a,b,c stiind ca :
2a×3+2b=c,c=6×6+3a,5a=50


va rog ajutati.ma este foarte urgent!!

Answer 1

5a = 50
a = 50:10
a = 5

c = 6×6 + 3a
c = 36 + 3*5
c = 36+15
c = 51

2a + 3 + 2b = c
2*5 + 3 + 2b = 51
10 + 3 + 2b = 51
13 + 2b = 51
2b = 38
b = 19

Answer 2

5a=50:5
a=10

c=6×6+3a
c=36+3×10
c=36+30
c=66

2a×3+2b=c
2×10×3+2b=66
6a+2b=66
2b=66-60
2b=6
b=3
