Question
The first step in finding the solution with elimination is,
3x + 9y = -9
-3x -y = 5
- Cross out the y and -y
- Cross out the 3x and -3x
- Change all the signs of the second equation
- Add -9 and 5
Hint:
In this question we have to find the first step in finding the solution with elimination . where the equations are 3x + 9y = -9 and -3x -y = 5. In elimination method , we have to multiply in both equation by number which is lowest common multiple for one of the variable. Then perform the addition or subtraction to eliminate the variable and substitute the that variable in equation and find the other equation.
The correct answer is: Cross out the 3x and -3x
Here we have to find the first step for the solution.
Firstly , the equations are
3x + 9y = -9 --(1)-
-3x -y = 5 --(2)
Now , Addition of equation(2) & equation(1) , we have
3x + 9y = 9
-3x - y = 5
____________
8y = 14
y = 7/4
The first step in finding the solution with elimination is cross out the 3x and -3x.
In this question, we have to find the first step but the equation is solved by the elimination method. In elimination method you have two equation. we have to multiply in both equation by number which is lowest common multiple for one of the variable. Then perform the addition or subtraction to eliminate the variable and substitute the that variable in equation and find the other equation.

When you graph the exact same equation twice,
An infinite solution can be produced if the lines are coincident and they must have the same y-intercept. The two lines having the same y-intercept and the slope, are actually the exact same line. In simpler words, we can say that if the two lines are sharing the same line, then the system would result in an infinite solution.
