stiind ca a-b=4, reyolvati ecuatiile, unde x este numar natural

a) x+2a-2b=8 b) x+1=30+5a-5b c) 5a-5b-x=10 d) x+16+8a-8b=49
ajutor va rog

a) x+2a-2b = 8 => x + 2x4 = x + 8 = 8 => x = 8-8 = 0.
b) x+1 = 30+5a-5b => x+1 = 30 + 5x4 = 30+20 = 50 => x+1 = 50 => x = 50-1 = 49.
c) 5a-5b-x = 10 => 5x4 - x = 10 => 20 - x = 10 => x = 20 - 10 = 10.
d) x+16+8a-8b = 49 => x+16+8x4 = 49 => x+16+32 = 49 => x + 48 = 49 => x = 49-48 = 1.

a=b+4
x+2b+4-2b=8
x+4=8/-4
x=4

x+1=30+5b+20-5b
x+1=50/-1
x=49

5b+20-5b-x=10
20-x=10
x=10

x+16+8b+20-8b=49
x+36=49
x=13

Coroana Te rog frumos
