Answer:
(D) Divide the first equation, , by 2.
Step-by-step explanation:
Given:
We need to find the operation performed on equation so as to get resultant equation as:
From Above we can see that there is no change in equation 2 with respect to resultant equation.
Also Resultant equation is simplified form of equation 1.
Simplifying equation 1 we get;
We can see that 2 is the common multiple on both side.
Hence we will divide equation 1 with 2 we get
which is the resultant equation.
Hence (D) Divide the first equation, , by 2 is the correct option.
Answer:
25
Step-by-step explanation:
The denominator may not equal 0, so you need to find where -2a+6 = 0.
This happens at a = 3, so 3 is the nonpermissible replacement.
