Algebra Ch 1 Review (Equations and Functions)

ax + c = R
(solve for x) 

• ax = R + c
• ax = R - c
• x = a(R-c)
• x = (R-c) / a

Solve:
C = 2πr, for r

• C/(2π) = r
• C + 2π = r
• C - 2π = r
• 2πC = r

a = b + c   , for  c

• c = a - b
• c = a + b
• c = ab
• c = a / b

Solve for x:
ax - b = c+d

• x = a(c + d + b) 
• x = (c + d) / (a-b) 
• x = a / (c + b + d)
• x= (c + b + d)/a

Solve for s: -2 = 4r + s

• s = -2 + 4r

• s = 2 - 4r

• s = -2 - 4r

• s = 2 + 4r
