B=4x - 2y
a. A- 1/2 B
3x+5y - 1/2 (4x-2y)
3x+5y-2x+y
=x+6y
b.4A + 3B
4 (3x+5y) + 3 (4x-2y)
12x+20y+12x-6y
=24x+14y
c.3A- 1 1/2 B
1 1/2 = 3/2
3(3x+5y) - 3/2 (4x-2y)
9x+15y-6x+3y
=3x+18y
= 3x + 5y - x + y
= 2x + 6y
4A + 3B = 4(3x + 5y) + 3(4x - 2y)
= 12x + 20y + 12x - 6y
= 24x + 14y
3A - 1 1/2B = 3A - 3/2B
= 3(3x + 5y) - 3/2(4x - 2y)
= 9x + 15y - 6x + 3y
= 3x + 18y
semoga membantu :)
