Answer:
Equations with one solution:
Equations with no solution:
Equations with infinite many solutions:
Step-by-step explanation:
We will solve each equation to see if it has one solution, no solution or infinite many solutions.
An equation where the value of variable can be found has one solution.
An equation with no solution has both sides different.
An equation with infinite solution will have both sides equal after solution(number)
So,
<u>Equation 1:</u>
5(x-2) = 5x-7
As both sides are not equal, equation has no solution.
<u>Equation 2:</u>
As both sides are equal the equation has infinite many solutions.
<u>Equation 3:</u>
As x=3, the equation has only one solution.
<u>Equation 4:</u>
The equation has no solution.
Hence,
Equations with one solution:
Equations with no solution:
Equations with infinite many solutions:
Answer:
x is equal to negative one, and y is equal to negative four.
Step-by-step explanation:
You can do this by solving one of the equations by either x or y, then substituting it into the other. Let's solve the second one for y:
Now we'll substitute that into the first equation:
So we now know that x is equal to -1. We can simply substitute that into one of the original equations to find y:
We now know that x is equal to -1, and y is equal to -4. We can also check our answer by plugging that -4 into the other equation, and see if we still get -1:
So we know that our answer is correct.
