To solve the linear equation , follow these steps:
Begin by applying the distributive property to the expression on both sides:
Substitute these results back into the equation:
Combine like terms:
Isolate the term with by subtracting 58 from both sides:
Now, solve for by dividing both sides by :
Simplify the fraction by dividing both numerator and denominator by 5:
Therefore, the solution to the equation is .
Solve for x:
\( 2(4-x)=8 \)
The parentheses must be eliminated first using the distributive property. You can't combine terms that are inside different parentheses until you distribute!
Write each step clearly! When you see , think: negative 7 times 6x equals negative 42x, and negative 7 times negative 2 equals positive 14.
Both terms have the same variable x, so you add their coefficients: . Think of it as combining like terms.
Fractions are common solutions! cannot be simplified further since 11 and 15 share no common factors besides 1.
Expand each part separately: and . Then verify the signs match your original expression.
