Solve the equation for b:
-11 + 3(b + 5) = 7

• b = 1
• b= -1
• b = 3
• b = -3

E = mc²     solve for m

• m = sqrt(E/c)
• m = sqrt(E)/c
• m = E/c²
• m = money

S = 3F - 24  Solve for F

• F = (S + 24)/3
• F = S/3 + 24
• F = 3S + 24
• F = 3(S + 24)

What is the definition of infinite solutions?

• no matter what constant is substituted in for the variable, the equation is ALWAYS true
• no matter what constant is substituted in for the variable, the equation will NEVER be true
• only this ONE solution will make the equation true
