Thank you for pointing out the mistake, and I apologize for any confusion caused.
1. y = 5x + 7
3y - 15x = 18
To convert the first equation to standard form, we move all terms to one side:
-5x + y = 7
The second equation is already in standard form.
This system has one solution because it consists of two linear equations with different slopes, meaning the lines representing them intersect at a single point.
2. y = 3x + 6
y = -13x - 4
Both equations are already in slope-intercept form (y = mx + b).
This system also has one solution since the lines represented by the equations have different slopes and intersect at one point.
3. x - 2y = 6
3x - 6y = 18
We need to rearrange the equations to standard form:
x - 2y = 6 -> -2y = -x + 6 -> 2y = x - 6
3x - 6y = 18 -> -6y = -3x + 18 -> 6y = 3x - 18
Simplifying these equations, we get:
2y = x - 6 -> x - 2y = 6
6y = 3x - 18 -> x - 2y = 6
This system consists of two equations representing the same line. Therefore, it has infinite solutions since any point on the line will satisfy both equations.
4. y = 23x - 1
y = 23x - 2
Both equations have the same slope-intercept form and represent the same line.
Similar to system 3, this system also has infinite solutions since any point on the line will satisfy both equations.
In summary:
1. One Solution
2. One Solution
3. Infinite Solutions
4. Infinite Solutions
