There are 2 unknowns
x = 2 or x = 2/5
no
You need another equation.
It is an equation and the value of x works out as 88
Yes.
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
-2
Double first equation: 2x + 2y = 4 Subtract this from second equation giving 5y = 5 so y = 1 and x = 1
It can't be solved because its discriminant is less than zero
if the 5x2y means 5x2y + 4x - 6 then yes it is a binomial but if the 5x2y means 5x * 2y + 4x - 6 then no it is not a binomial a nomial means one degree. a binomial means something to the second power. a polynomial means anything that has a 3rd power and greater.
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.
Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution.
