15+B=23 

subtract 15 from both sides 

-15+15+B=23-15

15 cancels out on the left and the answer is:

B=8

Hope this helps :)

Solve the system, or show that it has no solution. (If there is no solution, enter NO SOLUTION. If there are an infinite number
liberstina [14]

Answer:

The system has an infinite set of solutions (x,y) = (x, \frac{x-5}{4})

Step-by-step explanation:

From the first equation:

20x - 80y = 100

20x = 100 + 80y

x = \frac{100 + 80y}{20}

x = 5 + 4y

Replacing on the second equation:

-14x + 56y = -70

-14(5 + 4y) + 56y = -70

-70 - 56y + 56y = -70

0 = 0

This means that the system has an infinite number of solutions, considering:

x = 5 + 4y

4y = x - 5

y = \frac{x - 5}{4}

The system has an infinite set of solutions (x,y) = (x, \frac{x-5}{4})

What is the solution to -55+q=7<br><br> A. a=-62<br><br> B. q=62<br><br> C. q=42<br><br> D. q=-42
Scorpion4ik [409]

Answer:

C, as q = 62.

Step-by-step explanation:

When you have an equation, your goal is to get the letter you are solving for alone. To do this, you employ a simple rule: what you do to one side of the equals sign, you must do the other.

To isolate q in -55 + q = 7, you must add 55 to the left side. q is now alone. However, because we added 55 to the left side, we must also do it to the right! 7 + 55 = 62, so the new right side is 62. Hence, we get to this:

q = 62

The answer is now in plain sight!
