4y - 6y + 9y = -2
Combine like terms on the left side:
7y = -2
Divide each side by 7:
y = -2/7
The solution set is: { -2/7 }
0x2 + 1x - 7 = 0
x = 0 and y = 4
It is a linear equation in x. The equation has the solution x = 0.
The solution: x = 6/7 and x = -1
The equation 6 + y = 12 is a simple equation in one variable. If you add 6 to both sides of the equals sign, you get y = 18, and that is the solution.
0x2 + 1x - 7 = 0
There is no solution since the equation is inconsistent.
x = 0 and y = 4
The equation does not have a solution.
-5
Without an indication of the equals sign, this is not an equation.
Not sure what you mean; that equation certainly has a solution.
Given the equation 3x + 4 = 7, will there ever be more than one solution for x?
since a=5 you can put that into your equation of a+7=12 a=5 a+7=12 5+7=12 12=12 Correct So yes the given number is a solution to the given equation
It can't be solved because its discriminant is less than zero
It is a linear equation in x. The equation has the solution x = 0.
x = 19
