Answer: -2/3
Step-by-step explanation:
Two linear equations can have no solutions, exactly one solution or infinitely many solutions. There will be no solution if the lines are parallel on a graph. There will be exactly one solution if the lines intersect each other on a single point. And finally, there will be infinite solutions if the lines overlap each other perfectly.
A single line however has infinite ordered pair solutions as the line travels infinitely in both directions on the coordinate plane. For example, using the equation y=3x, for any real value of x, we will get a real value for y.
Linear inequalities with two variables have infinitely many solutions. We can use the inequality y>3x as an example. For any real value of x, we will get a real value for y.
I hope this helps!
Answer:
step 1: you subtract 28 and 3 to get 5x by itself
step 2:divide 25 and 5 to solve or x
step 3: x equals 5
Step-by-step explanation:
Well when you multiply a negative integer by a negative integer, it'll all ways be positive.
For example; - 34 × - 7 = 34 × 7 = (238)
The system of equations that model the situation is:
4c + 2s+ 3b == $29.51
c + 4s + 2b = $21.83
2c + 5s = $21.93
<h3>What are simultaneous equations?</h3>
