Answer:
56
Step-by-step explanation:
Isolate the variable (x). Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, subtract 5 from both sides:
13 (-5) = (x/7) + 5 (-5)
13 - 5 = x/7
8 = x/7
Isolate the variable x. Multiply 7 to both sides:
8(7) = (x/7)(7)
8(7) = x
x = 8 * 7
x = 56
56 is your answer for x.

Step-by-step explanation:
Answer:
add 11 and 7 togive you 18 and it is over 2.therefore the answer is 1/9
Answer:
No answer as written. 16 if we add an equals sign.
Step-by-step explanation:
As written, there is no "=" sign in either expression. That means they are only expressions, not equations. x can be anything. 10, 12345, 0.00000343345567788, etc. There is nothing that restricts the value of x.
If we set the two expressions equal to each other, we can calculate a value of x:
(2x + 30) = (5x - 18)
3x = 48
x = 16
