Question

. Solve 4 – 2q = -5(q + 1). Please show all of your work.
4+2q+5q-4=-5q+5q+ 5-4
7q=1
7q/7=1/7
q= 1/7
What did I do wrong?

Answer 1

you changed the sign of 2q

Answer 2

q should equal -3

Answer 3

andd you did that^

Answer 4

also you distributed your -5 incorrectly

Answer 5

4 - 2q = -5q-5

9 -2q = -5q

9 = -3q

q = 9/-3

q = -3

Answer 6

can u show me how you would of done the problem 4 – 2q = -5(q + 1)

Answer 7

4-2q=-5(q+1)
distribute the -5
4-2q=-5q-5
move the qs to one side
4=-5q-5+2q
move the constants to one side
4+5=-5q+2q
simplify:
9=-3q
divide by -3
-3=q
or
q=-3
