Błagam ratunku mam to na jutro Please !!! 2x+3=15 5x+9=-2x+4 2x+3 = 5x-4 3x-3 =x 2(x+4)+3=12x+5 3x-7=1/5x-2 2(x+8)-(5x-7)-8(8+x)=

2x + 3 = 15 2x = 15 -3 2x = 12 /;2 X = 6 5x + 9 = -2x + 4 5x + 2x = 4 - 9 7x = -5 /:7 x = -5/7 2x + 3 = 5x - 4 2x - 5x = -4 -3 -3x = -7 /:(-3) x = 7/3 3x - 3 = x 3x - x = 3 2x = 3 /:2 x = 3/2 2(x + 4) + 3 = 12x + 5 2x + 8 +3 = 12x + 5 2x -12x = 5 - 8 - 3 -10x = -6 /:(-10) x = 6/10 x = 3/5 3x - 7 = 1/5x - 2    /*5 15x - 35 = x - 10 15x - x = -10 + 35 14x = 25  /:14 x = 25/14 2(x + 8 ) - ( 5x - 7) - 8(8 + x) = 2x + 16 - 5x + 7 - 64 - 8x =  - 11x - 41
