Hello there, and welcome to Brainly!
In the following equation, you are solving for the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
First, add 14 to both sides of the equation:
7x - 14 (+14) = 35 (+14)
7x = 35 + 14
7x = 49
Next, divide 7 from both sides:
(7x)/7 = (49)/7
x = 49/7
x = 7
7 is the value for x that will make the equation true.
