Question

8-2(-x+1)=5-3(x+4)
15-3x=2(2x+4)
6(-x+6)-3=2(3x-1)-5

Answer 1

Solutiile la cele 3 ecuatii ...............

Answer 2

a) 8 - 2 (-x +1) = 5 -3(x +4)
8 +2x - 2 = 5 - 3x - 12
6 + 2x = -6 -3x
2x + 3x = -6 -6
5x = -12
x = -12/5

b) 15 - 3x = 2(2x + 4)
15 - 3x = 4x + 8
-3x - 4x = -15 + 8
-7x = -7
x = 1

c)6 (-x + 6) - 3 = 2(3x - 1) - 5
-6x + 36 - 3 = 6x - 2 - 5
-6x + 33 = 6x - 7
-6x - 6x = -33 - 7
-12x = -40
x=3, (3)
