Answer :
[tex] 3q + 5 = -2q + 20 [/tex]
add 2q to both sides.
[tex] 5q + 5 = 20 [/tex]
subtract 5 to both sides.
[tex] 5q = 15 [/tex]
divide 5 to both sides.
[tex] q = \frac{15}{5} [/tex]
the answer is: [tex]q = 3[/tex]
add 2q to both sides.
[tex] 5q + 5 = 20 [/tex]
subtract 5 to both sides.
[tex] 5q = 15 [/tex]
divide 5 to both sides.
[tex] q = \frac{15}{5} [/tex]
the answer is: [tex]q = 3[/tex]
