Find the value of the parameter X
To solve for in the equation , follow these steps:
On the left side:
(Combining the constants)
On the right side:
(Combining the terms)
Adding to both sides:
(Combining the terms)
Adding 18 to both sides to get rid of the constant on the right:
Dividing both sides by 19 to solve for :
Thus, the solution to the equation is .
Solve the equation
\( 5x-15=30 \)
Simplifying first makes the equation much easier to solve! Instead of dealing with 6 terms, you work with just 4 terms after combining like terms.
That's perfectly fine! You can move terms to either side. Just remember to change signs when crossing the equals sign and you'll get the same answer.
Like terms have the same variable part. In this problem: 74 and 3 are constants, while 8x and 5x both have x, so they combine to 13x.
Double-check your arithmetic! Make sure you combined like terms correctly:
You could try, but it's much harder! The standard method of isolating the variable by moving terms makes the solution clear and reduces errors.
