Question

-25=1/3n - 10 algebraic expression

Answer 1

-25=1/3n - 10

move -10 to the other side

sign changes from -10 to +10

-25+10=1/3n-10+10

-25+10=1/3n

-15=1/3n

multiply both sides by 3/1 to get n by itself

(-15)(3/1)=1/3n(3/1)

cross out 3 and 3 and 1 and 1, divide by 3 and 1

then becomes 1*1*1*1*n=n

(-15)(3/1)==45/1=-45

answer:

n=-45
