How many solutions are in 4(x-5)=3x+7

1 solution

This is an equation in only 1 variable (x ) thus will have only one solution

Solving to illustrate

4(x - 5) = 3x + 7 ( distribute left side )

4x - 20 = 3x + 7 ( subtract 3x from both sides )

4x - 3x - 20 = 7

x - 20 = 7 ( add 20 to both sides )

x = 7 + 20 = 27 ( one solution )

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
