a.) 3(2x-1)+4(1-x) = 6x - 3 + 4 - 4x = 2x + 1
b.) 2( 2x+5)-6(x-2) = 4x + 10 - 6x - 12 = -2x - 2
c) -2x(8-x)-5(x2+3x)= -16x+4x²-5x²-15x = -31x-x²
d.) 5(3-2x)-(4x+6)*3 = 15 - 10x -4x + 6 * 3 = 15 - 14x + 18 = 33 - 14x
e) 2x+5-3x-12/3= ⅖x+5/3-x-4 = -⅓x-2⅓
f.) 12x+16/4- 10x+15/ 5 = 3x + 4 - 2x + 3 = x - 1
g.) 9-6x/ 3- 21-14x/7 = 3 - 2x - 3 - 2x = 0
h.) 4(x-1)/ 2-3* 10x-50/5 = 4x - 4 : 2 *3 - 10x - 50 : 5 = 2x - 2 *3 - 2x - 10 = 6x - 6 - 2x - 10 = - 4x - 4
