Question

Two numbers add to 436 and the front is 134 bigger than the second. What are the two numbers?

Answer 1

Lets say x is the smaller number and y is the bigger number.

x + y = 436

x + 134 = y

We can substitute the second equation into the first (substitute x + 134 in for y)

x + (x+134) = 436

2x + 134 = 436

2x = 302

x = 151

We can now plug this back into either formula (i use the second)

151 + 134 = b

b = 285

The 2 numbers are 151 and 285

Answer 2

Take away 134 from the total, so that both numbers are of equal value:

436 - 134 = 302

Divide by 2 to find the smaller number:

302 ÷ 2 = 151

Add back the 134 to find the bigger number:

151 + 134 = 285

Answer: The two numbers are 151 and 285
