y = -0.5x plus or minus any number
It is a quadratic equation with one unknown variable, x which has no real roots.
A quadratic equation, if there's an equals stil to come... Otherwise it's just an expression.
Add 5 to both sides of the equation to get rid of the - 5. -3x - 5 + 5 = -20 + 5 Solve and simplify. -3x = -15 Divide both sides of the equation by -3. x = 5
x=-1 ^ how do you know?
The required equation is: -7x = 63
x = 4 and y = 7
An equation where x equals 3.
x = 4 and y = 7 which will satisfy both equations
i think its 10
15x minus 8=minus 180 3x+8=24
Yes that is correct
The equation has infinitely many solutions.
