pls tell me I am not the only person who sucks at math :|
*pls answer correctly tho. it'd be nice O_O....yes brainlest and ect.. are included*
Consider this equation and the steps taken to solve it.
–9(a – 5) = –18 (distribute)
–9a + 45 = –18 (subtract 45)
–9a = –63 (divide by –9)
a = 7
What steps might you take to verify the solution? Check all that apply.
A) Substitute 7 for a.
B) Pick any value for a and substitute.
C) Simplify the equation after substituting the value for a.
D) Verify that a = 7 is correct when the result is a true statement.
E) Verify that a = 7 is correct when the result is a false statement.
