Brain chooses an integer, multiplies it by 4 then subtracts 30. He then multiplies his answer by 2 and finally subtracts 10. His answer is two digest number. What is the largest integer he cold have chosen?

(lots of working's out plz)

thx =]

4x-30=2-10

4x= 2-10+30

4x= 2-40

4x=-38

x-38/4

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5
