6s+4d=$53

4s+6d=$47

Multiply 6 in the first equation which is

36s+24d=$318

Multiply -4 in the second equation which is

-16s-24d=$-188

Then..

36s+24d=$318

-16s-24d=$-188

You cancel out the -24d and +24d

36s=$318

-16s=$-188

Do the math..

20s=$130

Divide 20 by both sides and answer...

s=$6.5

Rewrite in simplest terms: -2(5d-9f)+7f-10(-9f-7d)
Afina-wow [57]

Answer:

= 5 ( 12d + 23f )

Step-by-step explanation:

-2(5d-9f)+7f-10(-9f-7d

Open parenthesis

= -10d + 18f + 7f + 90f + 70d

Collect like terms

= -10d + 70d + 18f + 7f + 90f

= 60d + 115f

Factorise

= 5 ( 12d + 23f )

Therefore,

-2(5d-9f)+7f-10(-9f-7d) in its simplest form is 5 ( 12d + 23f )
