What Is X In 2x 2 8y 121 5

The values of x that satisfy the equation are called solutions of the equation, and roots or zeros of the expression on its left-hand side. A quadratic equation has at most two solutions. If there is only one solution, one says that it is a double root. start with 2 equations in 2 unknowns . 2x^2+8y=121.5. x^2 -8y=121.5. add the 2 equations and we get . 3x^2 = 243. x^2 = 81 so x= +9 or -9. We can solve for y by plugging in these values of x in one of the equations . I will strait with the second since it is simpler (9)^2 -8y= 121.5. 81-8y =121.5

What Is X In 2x 2 8y 121 5Algebra. Solve for x x^2-8y=121.5. x2 − 8y = 121.5 x 2 - 8 y = 121.5. Add 8y 8 y to both sides of the equation. x2 = 121.5+8y x 2 = 121.5 + 8 y. Take the specified root of both sides of the equation to eliminate the exponent on the left side. x = ±√121.5+8y x = ± 121.5 + 8 y. Simplify ±√121.5+8y ± 121.5 + 8 y. Tap for more steps.

Expert-Verified Answer. question. 9 people found it helpful. ahmedishaal. 2x² +8y = 121.5. 8y = 121.5 - 2x². and, x²-8y = 121.5. -8y = 121.5 -x². 8y = x²-121.5. Now, equate the two 8y's. 121.5-2x² = x² -121.5. -3x² = -121.5-121.5. -3x² = -243. 3x² = 243. x² = 81. x = ±9. arrow right. Explore similar answers. messages.
