a) 6(2a - 6b + 3c) = 12a -36b +18c
b) (3x - 2y +9 )4 = 12x -8y +36
c) 3(5x - 8z -2) = 15x -24z -6
d) (4x -7y +7) (-2) = -8x +14y -14
e) -8 (7n +9p + t) = -56n -72p -8t
f) -2 (3a +1) + (4a -5) = -6a -2 +4a -5 = -2a -7
g) 3 (b -5a) -2 (3b+a) = 3b -15a -6b -2a = -17a -3b
h) 5( 2x+3y) - (x - 2y) = 10x +15y -x +2y = 9x +17y
a) 6(2a-6b+3c)=12a-36b+18c
b) (3x-2y+9)4=12x-8y+36
c) 3(5x-8z-2)=15x-24z-6
d) (4x-7y+7)(-2)=-8x+14y-14
e) -8(7n+9p+t)=-56-72p-8t
f) -2(3a+1)+(4a-5)=-6a-3+4a-5=-2a-8
g) 3(b-5a)-2(3b+a)=3b-15a-6b-2a=-3b-17a
h) 5(2x+3y)-(x-2y)=10x+15y-x+2y=9x+17y
