Answer:

x = 4

Step-by-step explanation:

Equation: 3x + 13 = 25

      3x = 12

Step 2: Divide both sides by 3.

<u>3x</u>   =  <u>12</u>

algol [13]

Answer:  76 Sodas and 40 hot dogs

Step-by-step explanation:

Let S and H represent the numbers of Sodas and Hot dogs.

We are told that:

S + H = 116

We also see that:

H = S - 36

==

Take the second equation's value for H (S - 36) and use it in the first:

S + H = 116

S + (S-36) = 116

2S = 152

S = 76

and therefore H = S - 36, or 40.

76 + 40 = 116  [Checks]

76 Sodas and 40 hot dogs
