Mrs boyle buys 2g pounds of beef, mrs anand buys 1.5 pounds less than mrs boyle, if mrs anand buys d pounds of beef, express d in terms of g

Mrs. Boyle: 2g pounds of beef
Mrs. Anand: 1.5 pounds less that that bought by Mrs. Boyle = 2g-1.5
However, the amount of beef bought by Mrs. Anand is equivalent to "d"
Therefore,

d=2g-1.5

I’m not sure how this works

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,                                                                    

0 = ( 2 - 4 ) ( p + q )0 = ( 2 - 4 ) ( 2 + 5 i ),   by multiplying these0 = ( 4 + 10 i - 8 - 20 i )0 = 4 - 8 + 10 i - 20 i0 = - 4 -10 i   0 = 2 ( - 2 - 5 i )0 / 2 = - 2 - 5 i- 2 - 5 i = 0- 5 i = 2i = 2 / - 5
