Answer:
x = 2
Step-by-step explanation:
-3 +6x = 25 -8x
Add 8x to each side
-3 +6x+8x = 25 -8x=8x
-3+14x = 25
Add 3 to each side
-3+3+14x = 25+3
14x = 28
Divide by 14
14x/14 = 28/14
x = 2
If there are 20 rows each and 15 per row then you would multiply 20(15) = 300 then so there are 300 seats in Section J. each seat is 18$ so you would multiply 300(18) = 5400 so section J would get 5,400$ if it were to be sold out. The equation is 20(15)=300(18)=5400

x−2=13
First find the value of x
x-2+2 = 13+2
x = 15
Now substitute into the expression
x^2 -4x+4
15^2 -4*15+4
225 - 60+4
165+4
