➷ 847) You need to cross multiply
Multiply both sides by (x - 7) and 3
This is what you should get:
Now we just need to get like terms on the same side.
Add 42 to both sides and subtract 2x from both also
Now you get this:
848) It's the same principle in this one too.
Multiply both sides by (x - 13) and 11
You should get:
Subtract 11x from both sides and add 156 also
Now you get:
849) Multiply both sides by x
You should get:
Add 4x to both sides and add 12 also:
Divide both sides by 5
850) Multiply both sides by x
You should get:
Subtract x from both sides:
Divide both sides by 3:

Answer:
y = -4/5x + 3
Step-by-step explanation:
Chose any two points on the line:
(5, -2)
(-5, 6)
Slope = (y2 - y1) / (x2 - x1)
6 -(-2) / -5 - 5
8 / -10
-4/5
Equation:
y = mx + b
Plug in x and y using any coords and then plug in m (the slope):
-2 = -4/5 * 5 + b
-2 = -20/4 + b
-2 = -5 + b
Add 5 on both sides:
3 = b
Now our equation is:
y = -4/5x + 3
Please let me know if I've done something wrong!
<u>Methods to solve rational equation:</u>
Rational equation:
A rational equation is an equation containing at least one rational expression.
Method 1:
The method for solving rational equations is to rewrite the rational expressions in terms of a common denominator. Then, since we know the numerators are equal, we can solve for the variable.
For example,
This can be used for rational equations with polynomials too.
For example,
When the terms in a rational equation have unlike denominators, solving the equation will be as follows
Method 2:
Another way of solving the above equation is by finding least common denominator (LCD)
Factors of 4:
Factors of 8:
The LCD of 4 and 8 is 8. So, we have to make the right hand side denominator as 8. This is done by the following step,
we get,
On cancelling 8 on both sides we get,
Hence, these are the ways to solve a rational equation.
Answer is A...first one y = -5x - 7
