Solving for d: d = -4.7 satisfies the equation.
the first step in solving the equation is to subtract the nine from the three. you will get negative 6.
Subtract 1 form both sides of the equation
Solving the equation for "y" gives you the slope-intercept form.
Solving tne simultaneous equation gives x = 19.8 and y = -2.2
The equation soild plus gas equals a liquid
It can't be solved because its discriminant is less than zero
Double first equation: 2x + 2y = 4 Subtract this from second equation giving 5y = 5 so y = 1 and x = 1
x = 2 or x = 2/5
That looks like a linear equation (no quadratic or higher terms), so you can expect it to have a single solution. However, actually solving the equation is not difficult; do it, to confirm this.
