Answer:

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


You have 2 separate equations. PLESASE MARK BRAINLYIEST


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

Step-by-step explanation:


Answer:

When Q = 16 then B + 3 = 0

Step-by-step explanation:

When Q = 16 then B + 3 = 0

Step-by-step explanation:

It is given that

Q + B = 13

To find the value of B

We know that Q + B = 13

From this we get value of B

B = 13 - Q

To find the value of Q

We have to find  when B + 3 =0

13 - Q + 3 =0  

Q = 16

When Q =16 then

B + 3 =0
