Question

If 4 is added to twice a number and this sum is multiplied by 5, the result is the same as if the number is multiplied by -8 and 2 is added to the product. What is the number?

Answer 1

let the number be x
4 is added to twice a number= 4+2x
the sum is multiplied by 5= 5(4+2x)
the result is the same as if the number is multiplied by -8 and 2 added= 5(4+2x)= (-8x)+2
so now you have
5(4+2x)=(-8x)+2 so now solve for x

Answer 2

ok

Answer 3

Is -1 the answer

Answer 4

5(4+2x)=(-8x)+2
first open up the brackets
20+10x=-8x+2
collect like terms
10x+8x=2-20
now simplify

Answer 5

oh sorry you are right

Answer 6

-1 is the answer
