Question

a) 6x + (2x – 4) – 2 = (R: 8x -6)
b) 7y -8 – (5y – 3) = (R: 2y -5)
c) 4x – ( -3X + 9 – 2X) = ( R: 9x – 9)
d) 3x – (-2x + 5) – 8x + 9 = (R: -3x + 4)
e) 4x – 3 + (2x + 1) = (R: 6x -2)
f) (x + y) – (x + 2y) = (R: -y)
g) ( 3x – 2y) + (7x + y) = (R: 10x – 19)
h) –(8a + 4 – ( 3a + 2) = (R: -11a -6)

Answer 1

a)6x+(2x-4)-2=
6x+2x-4-2
8x-6

b)7y-8-(5y-3)=
7y-8-5y+3
2y-5


c)4x-(-3x+9-2x)
4x+3x-9+2x
9x-9

d)3x-(-2x+5)-8x+9
3x+2x-5-8x+9
-3x+4
