Question

Enter the value of n so that the expression (5y - 2.3) + (-2y -4.3)
is equivalent to (3y-n).

Answer 1

Explanation:

(5y - 2.3) + (-2y - 4.3) = 3y - n Remove the brackets

5y - 2.3 - 2y - 4.3 = 3y - n Combine like terms

3y - 6.6 = 3y - n Subtract 3y from both sidess

- 6.6 = - n Divide by - 1

6.6 = n
