Question

2 thirds times a number plus 7 equal 7 minus the number. find the number?

Answer 1

perhaps yu sed (2/3)(x+7)=7-x

(x+7)=-(3/2)(x-7)

x+7=-(3/2)x +10.5

(5/2)x=10.5 -7=3/5

x=(2/5)*(3/5)

x=6/25

x=0.24

Answer 2

2/3x+7=7-n

U FLIP IT!!

-n+7=2/3x+7

so you add -7 to both sides because its the opposite sign, they both cross out and you're left with -n=2/3x

divide -n/2/3 *-n is really -1*

2/3 times -1  is -2/3

when you divide u flip the fraction but its only a one so you multiply either way 2/3*-1/1 would be -2/3

x=-2/3

 

if this isn't the answer it would be 42...because the equation would be 2/3x+7=n-7 and when you solve this it equals 42.

But to me -2/3 is the answer, I'm not sure if 42 is the answer but trust me your find out...
