Explanation:

step 1: distribute 8.02 into the numbers inside the parentheses

step 2: move the constant to the right side and change its sign

48.12 s=20-160.4

step 3: subtract

48.12= -140.4

step 4: divide both sides by 48.21

and bam the answer will be

Answer:

-2.918

Explanation:

8.02(20+6s)= 20

Multiply everything in bracket you have:

160.4+48.12s = 20

Collect like terms

48.12s = 20-160.4

s= (20-160.4)÷ 48.12

s= -2.918
