(1) a+-+8+=+5%2A%28b+-+8%29

(1) a+-+8+=+5b+-+40

(1) 5b+-+a+=+32

and

(2) a+-+5+=+3%2A%28b+-+5%29

(2) a+-+5+=+3b+-+15

(2) 3b+-+a+=+10

Subtract (2) from (1)

(3) 2b+=+22

(3) b+=+11

Substitute this back in (1) or (2)

(1) 5%2A11+-+a+=+32

(1) a+=+55+-+32

(1) a+=+23

Step-by-step explanation:

for the points! : )

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
