solvefor X,Y=X4-2X3+5X2-4

solve for

X, Y = X 4 - 2 X 3 + 5 X 2 - 4

X = \frac{Y + 4}{8}

Solution steps

Y = X \cdot 4 - 2 X \cdot 3 + 5 X \cdot 2 - 4

Switch sides

X \cdot 4 - 2 X \cdot 3 + 5 X \cdot 2 - 4 = Y

Multiply the numbers:

2 \cdot 3 = 6

4 X - 6 X + 5 \cdot 2 X - 4 = Y

Multiply the numbers:

5 \cdot 2 = 10

4 X - 6 X + 10 X - 4 = Y

Add similar elements:

4 X - 6 X + 10 X = 8 X

8 X - 4 = Y

Move

4

to the right side

8 X = Y + 4

Divide both sides by

8

X = \frac{Y + 4}{8}

2 m - 5 = 65

0.11 y = 1.5 + 0.1 y

(x + 3) 2 = 49

12 x = 3

\frac{x - 2}{3} = \frac{x + 2}{4}
