Question

Rezolvati urmatoarele ecuatii si inecuatii.a)4(x-9)=4 b)5(x+3)=27+23 c)3x+2(x+5)=23 d)7x+3(x+2)=16 e)11+14=3(x-1)+16 f)13(x-2)-2x=7 Va rog frumos

Answer 1

a) 4x -36=4 , 4x = 40, x = 40 supra 4, x = 10 C)3x +2x +10 = 23 , 5x = 13, x = 13 supra 5 b) 5x +15= 50, 5x= 35. X= 7 d) 7x+3x+6= 16 , 10 x =10, x=10 supra10, x=1
