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
If: 2^x2 +5x = k Then: 2x^2 +5x -k = 0 Using and solving the discriminant: k = -3.125 Using and solving the quadratic equation: x = -1.25 Check: 2(-1.25)^2 +5(-1.25) = -3.125
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.
Solving the equation for "y" gives you the slope-intercept form.
Subtract 1 form both sides of the equation
Solving tne simultaneous equation gives x = 19.8 and y = -2.2
-2
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
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.
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.
