Hello from MrBillDoesMath!
Answer:
a = 2.7
Discussion:
(2/3) ( 6a + 9 ) = 16.8 => the Distributive law
(2/3) (6a) + (2/3)9 = 16.8 =>
4a + 6 = 16.8 => subtract 6 from both sides
4a = 16.8 -6 = 10.8 (divide both sides by 4)
a = 10.8/4
= 2.7
Thank you,
MrB

Answer:
q = 29/2 ( decimal: q = 14.5)
Step-by-step explanation:
multiply both sides by 5
5 * 2/5 (q - 7) = 3 * 5
simplify
2 (q - 7) = 15
divide both sides by 2
(2 (q - 7))/(2) = 15/2
simplify
q - 7 = 15/2
add 7 to both sides
q - 7 + 7 = 15/2 + 7
simplify
q = 29/2
