99 points show your work q+b=13. when b+3=0

Q+B=13. When B+3=0

You have 2 separate equations.

First solve the 2nd equation for B:

B +3 = 0

Subtract 3 from both sides:

B +3 - 3 = 0-3

Simplify:

B = -3

Now we have a value for B, we can replace b with -3 in the first equation and solve for Q:

Q + -3 = 13

Add 3 to each side:

Q + -3 + 3 = 13+3

Simplify:

Q = 16

So you have Q = 16 and B = -3

Question

SHOW YOUR WORK Q+B=13. When B+3=0

16 + (-3) = 13

Step-by-step explanation:

find b

B + 3 = 0

B = -3

now we have the expression:

Q + (-3) = 13

Q = 13 + 3

Q = 16

check

16 + (-3) = 13

16 = 16

i think it is 70
