Ответ:
2n= 12
divide both sides by 2
n=6
Ответ:
n=6
Step-by-step explanation:
addition property of equality is adding the same number to both sides of equation does not change the equation.
distributive property: a(b+c)=ab+ac
add 5 both sides of an equation
2n-5+5=7+5
2n=12
divide 2 both sides of an equation.
2n/2=12/2
simplify.
12/2=6
12/6=2
6*2=12
2*6=12
n=6
Hope this helps!
Thanks!
Have a great day!
