solvefor x,P=2x4-x3+2x2-k

solve for

x, P = 2 x 4 - x 3 + 2 x 2 - k

x = \frac{P + k}{9}

Solution steps

P = 2 x \cdot 4 - x \cdot 3 + 2 x \cdot 2 - k

Switch sides

2 x \cdot 4 - x \cdot 3 + 2 x \cdot 2 - k = P

Multiply the numbers:

2 \cdot 4 = 8

8 x - 3 x + 2 \cdot 2 x - k = P

Multiply the numbers:

2 \cdot 2 = 4

8 x - 3 x + 4 x - k = P

Add similar elements:

8 x - 3 x + 4 x = 9 x

9 x - k = P

Move

k

to the right side

9 x = P + k

Divide both sides by

9

x = \frac{P + k}{9}

x - (7 - x) = 5 (x + 1) + x

85 = 191 - U

x, 5 y = 8 x

4 (\frac{2 - 7 y}{21}) + y = 1

X, A X = B
