If you're using substitution, solve for the first variable in one of the equations, then substitute the result into another equation. your answer is no solution:
x = 2 ; y = 6
4x = 18 - y
4 (2) = 18 - 6
8 = 12
8 does not equal 12, there is no solution

Answer:
x = 12
y = 13
Step-by-step explanation:
Let's assume the two numbers as x and y.
The sum of the two numbers is 25
So,
The product of the two numbers is 156
- xy = 156
- x(25 - x) = 156
- 25x - x² = 156
- x² - 25x + 156 = 0
- x² - 13x - 12x - 156 = 0
- (x - 12) • (x - 13) = 0
- x - 13 = 0
- x = 13
- x - 12 = 0
- x = 12
Hence, the two numbers are 13 and 12.
