6x - 2y = 5 3x - y = 10 Solve the system of equations. (3, -1) no solution
6x - 2y = 5 (equ. 1) 3x - y = 10 multiply 2 on both sides the result is: 6x - 2y = 20 (equ. 2) subtracting equ. 1 and 2 the result is: 0 = -15 which is false There is no solution for the system 6x - 2y = 5 3x - y = 10.

6x - 2y = 5 (equ. 1)
3x - y = 10 multiply 2 on both sides the result is:
6x - 2y = 20 (equ. 2)
subtracting equ. 1 and 2 the result is:
0 = -15 which is false
There is no solution for the system 6x - 2y = 5 3x - y = 10.

The equation 2 - 3y + 6x = 0 written in slope-intercept form is y = 2x + 2/3 .
2 - 3y + 6x = 0
3y = 2 + 6x
y = 2x + 2/3

Write the standard form of the line with the given information. Include your work in your final answer. Type your answer in the box provided or use the upload option to submit your solution. The line containing a slope of 3 and a y-intercept of -2. User: The equations of two lines are x - 3y = 6 and y = 3x + 2. Determine if the lines are parallel, perpendicular or neither. parallel perpendicular neither
Weegy: neither since the slope of the first equation is (1/3) and the second has 3. if one of these is negative then we have perpendicular but they are both positive User: Find the slope of the following graph. 3 1/3 -3 Weegy: We cannot graph for you on Weegy.
