Final answer:
To translate Delia's age increased by 18 is 70 into an equation, we can write x + 18 = 70 and solve for x.
Step-by-step explanation:
To translate this sentence into an equation, we can let 'x' represent Delia's age. The sentence 'Delia's age increased by 18 is 70' can be written as:
x + 18 = 70
To solve for 'x', we need to isolate it on one side of the equation. We can do this by subtracting 18 from both sides:
x + 18 - 18 = 70 - 18
x = 52
Therefore, Delia's age is 52 years old.
