I just know that 2 is X = 6

Answer:

for the first one, it's x=11. first, you have to subtract 6 from both sides (-2x+6-6=-16-6) then you simplify that so you get -2x=-22, and from there you divide both sides by -2

getting -2x/-2=-22/-2 then you simplify that and get x=11

and for the second one x=-7. first, you have to add 10 to both sides

(-10+5x+10=-45+10) then simplify that down to 5x=-35 then divide both sides by 5 (5x/5=-35/5) then simplify that down to x=-7

266 tickets were the combined amount of adult and child tickets sold.

Step-by-step explanation:

Adult tickets sold = 152

Ratio of adult tickets to child tickets sold = 4:3

We need to find combined amount of adult and child tickets sold.

First finding child tickets sold making a proportion.

Let child tickets sold = x

4:3=152:x

Solving:

$\frac{4}{3}=\frac{152}{x}$

Cross multiplying:

$4x=152*3$

$4x=456$

Divide both sides by 4

$x=114$

So, the Child tickets sold are: 114

Combine amount of adult and child tickets sold = 152+114 = 266

So, 266 tickets were the combined amount of adult and child tickets sold.
