User: x + y = 6 x - y = 8 Solve the system of equations.

Weegy: 6 ( x - 3 ) = 30

6x - 18 = 30

6x = 30 + 18

User: x + y = 6 x - y = 8 Solve the system of equations.

Weegy: 6 ( x - 3 ) = 30

6x - 18 = 30

6x = 30 + 18

6x = 48

x = 8

User: sytem of equations

User: The slope of the line whose equation is 3x - 2y = 4 is

Weegy: The answer is B=3/2. To find the slope of this line, first rearrange the equation to slope intercept form which is y=mx+b where m is the slope. [ After rearranging it, we get 2y=3x- 4.......divide by 2 to get y by itself......which in turn leaves us with y=1.5x- 2........therefore the slope is 1.5, or 3/2. ]

If a = -12/5, then 5x + 2y = 6 and 3x - ay = 4 are parallel. FALSE.
For 5x + 2y = 6, the slope is -5/2;
For 3x - ay = 4, the slope is 3/a, when a = -12/5, slope = 3(-5/12) = -5/4
The slope of two lines are not the same so they are not parallel.

2x - 6y = 5
x + y = 2 - > y = 2 - x
Replace y with 2 - x in the first equation:
2x - 6(2 - x) = 5,
Simplify and solve the equation: x = 17/8
y = 2 - (17/8) = - 1/8
The solution for 2x - 6y = 5 x + y = 2 is (17/8, - 1/8)

The slope of the line that passes through the points (2, 1) and (-4, -5) is m = (-5 -1)/(-4 -2) = 1

x + y = 6
x - y = 0
Adding two equations above: 2x = 6, so x = 3
y = x = 3
The solution set for the system of equations x + y = 6, x - y = 0 contains one point (3, 3)

The y-intercept of the line whose equation is 3x + 2y = 7 is 7/2.
3x + 2y = 7
2y = -3x + 7
y = (-3/2)x + 7/2 which is the slope intercept form.

6x - 2y = 5 (the 1st equation)
3x - y = 10 multiply 2 on both sides:
6x - 2y = 20 (the 2nd equation)
Subtracting the first and the second equation: 0 = - 15
Therefore, there is no slution for the system of equations 6x - 2y = 5 3x - y = 10

x + y = 6
x - y = 8
Add the above two equations: 2x = 14, x = 7
7 + y = 6, so y = -1
The solution for the system of equations x + y = 6, x - y = 8 is (7, -1)
