Amazing good job you did great
Answer:
see below
Step-by-step explanation:
9 is the difference of a number n and 7.
Let's break this down.
"is" represents the equal sign.
"the difference" represents subtraction.
9 = n - 7
Now let's solve the equation.
9 = n - 7
Add 7 to both sides.
16 = n

3(x−5)/2=2(x+5)/3
Cross-multiply.
(3(x−5))/2=(2(x+5))/3
3(x−5)*(3)=2(x+5)*(2)
9x−45=4x+20
Subtract 4x from both sides.
9x−45−4x=4x+20−4x
5x−45=20
Add 45 to both sides.
5x−45+45=20+45
5x=65
Divide both sides by 5.
5x/5=65/5
x=13
Numbers that cannot be expressed as an exact ratio are called irrational numbers so that would make it true
