To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: Apply the distributive property
The given equation is .
First, distribute :
.
Insert this into the equation:
.
Step 2: Simplify the equation
Combine like terms (the terms and constants):
.
.
So, the equation becomes:
.
Step 3: Solve for
Add 19 to both sides to isolate the -term:
.
.
Divide both sides by 7:
.
Simplifying this gives .
Therefore, the solution to the problem is .
\( 5x=1 \)
What is the value of x?
Remember the rule: negative × negative = positive! When you distribute -4 into (6-x), you get -4×6 = -24 and -4×(-x) = +4x.
Divide 33 by 7: 33 ÷ 7 = 4 remainder 5. So . The quotient becomes the whole number, remainder becomes the new numerator.
Either order works fine! You can combine -24 + 5 = -19 first, then 4x + 3x = 7x, or vice versa. The important thing is to combine all like terms.
Not necessarily! Both and are correct. Mixed numbers are often preferred for final answers because they're easier to visualize.
You can work backwards! Start with your answer x = 33/7, then work through each step in reverse. But substitution into the original equation is the most reliable check.
