Answer:
Step-by-step explanation:
Let x = the age of Thomas
Let x + 6 = the age of Huilan
x + x + 6 = 70
2x + 6 = 70
2x = 64
x = 32 years
x+6 = 38 years
Combine like terms on both sides of the equation. Isolate the x term by subtracting 2x from both sides. ... The solution x = 0 means that the value 0 satisfies the equation, so there is a solution. “No solution” means that there is no value, not even 0, which would satisfy the equation.
Answer:
Step-by-step explanation:
15 - x > 0
-x > -15
x < 15
if x < 15 15-x
if x = 15 0
if x > 15 x-15
