The researcher exercise direct control over at least one variable.
When you are doing distributive property, it can only happen if a number or exponent is before the bracket. From this equation, you can solve for x like so:
7(x+5)-x=42
7x+35-x=42 -Using distributive property (Multiplication)
6x=7 -Collecting like terms.
x= 7/6 -The answer.
Therefore x would equate to 7/6.
