Equations for x

100

4x + 3 = 11

x = 2

200

3(x + 4) = 48

x = 12

300

4x - 2 = 3x + 4

x = 6

400

6x = 8 - 9 + 6x

No Real Solution

500

2x + (1/5) = (3/5)

x = 1/5

Solve for a Variable

100

d = rt Solve for t

d/r = t or t = d/r

200

T + M = R Solve for T

T = R - M

300

ax + r = 7 Solve for r

r = 7 - ax

400

PV = nRT solve for T

T = (PV)/nr

500

PV = nRT Solve for R

R = (PV)/nT
