Question

a) -2x-(x-17)=34-(-x 25)

b) 17x-(-16x-27)=2x 43

c) -2x-3(x-17)=34-2(-x 25)

d) 17x +3(-16x-37)=2x 43-4x

Answer 1

a) -2x - (x-17) = 34-(-x + 25)

-2x- x+17= 34+x-25

-2x-x-x= -17 +34-25

-4x = -8

x = 2

b)17x-(-16x-27) = 2x+43

17x + 16x + 27 = 2x + 43

17x + 16x -2x= -27 +43

31x= 26

x= 21/31

c)- 2x- 3(x-17) = 34- 2(-x + 25)

-2x - 3x + 51 = 34 + 2x -50

-2x - 3x -2x = -51 + 34 -50

-7x = -67

x = 67/7

d) 17x +3(-16x-37) = 2x+ 43 -4x

17x -48x -111 = 2x + 43 -4x

17x - 48x -2x + 4x = 111 -43

-29x = 68

x = -68/29
