Answer:
-4.
Step-by-step explanation:
-4x - 15 = -4x + 6
has no solution.
Answer:
y = -1/3x - 4 (slope-intercept form)
or
x + 3y = -12 (Standard form).
Step-by-step explanation:
The slope of the line = (-3 - (-2)) / (-3 - (-6))
= -1 / 3.
Using the point-slope form of straight line:
y - y1 = m(x - x1) we have:
y - (-2) = -1/3(x - -6))
y + 2 = -1/3(x + 6
y + 2 = -1/3x - 2
y = -1/3x - 4
In standard form (multiplying thru by 3):
3y = -x - 12
x + 3y = -12.
Answer:
It has a single solution x=-3 y=26
Step-by-step explanation:
The ratios of coefficients of x and y are different, so the pair of equations has one solution. It is easy to tell the first offered solution (15, 17) does not satisfy the first equation, so that choice is eliminated.
Fortunately, the second offered solution, (x, y) = (-3, 26), satisfies both equations.
The equations have a single solution: (x, y) = (-3, 26).
Answer: other than 7
Step-by-step explanation:
Given
Equation is 
For an equation to have no solution, the missing number can be any number other than 7
because if we put 7 then it justifies the equation i.e. 
while on the other hand for a number other than 7, it does not justify the equation.
