Variables on Both Sides

100

5x + 11 = 3x + 15

x = 2

200

-2x + 5 = 6x - 35

x = 5

300

7x - 13 = -2x - 103

x = -10

400

6(3x - 4) = 5(4x - 2)

x = -7

500

-4x + 11 + 7x + 14 = 2(x + 4) + 4(2x - 1)

x = 3

Quadratics

100

3x² + 2 = 50

x = 4 or -4

200

x² /5  - 30 = 50

x = 20 or -20

300

10x² - 111 = 7x² + 132

x = 9 or -9

400

-2(x² + 3) + 4x² - 7 = 37

x = 5 or -5

500

9(x - 3)² + 16 = 916

x = 13 or -7

Literals

100

e + ri = c

Solve for e

e = c - ri

200

px - w = v

Solve for x

x = (v + w) / p

300

4x - 8y = 20

Solve for x

x = 5 + 2y

400

9a - 3b = 42

Solve for b

b = -14 + 3a

500

mo² - l = y

Solve for o

o = sqrt[ (y + l) / m   ]

Inequalities
