Question

if 3a minus 9 equals 6, what is the value of 5a plus 2?

Also,
if 2x plus 1 equals 5, what is the value of 3x minus 4?

Answer 1

\[3a-9=6\]?

Answer 2

@satellite73 Its from Algebra one, and its solve each equation, then check your solution.

Answer 3

ok fine, i was just asking if the first equation was \(3a-9=6\)

Answer 4

yes @satellite73

Answer 5

ok, then to solve for \(a\) you need to first add \(9\) to both sides,
what do you get ?

Answer 6

0 and 15

Answer 7

yeah but actually it is \(3a=15\) when you add, since the \(3a\) is still there on the left

Answer 8

to solve \(3a=15\) you can either a) divide by 3, or b) think, "three times what number gives 15?"
