Question

three timesa number and 5 times another number added together make 169.when 5 times the first number and three times the second number added together make 159
a) write the given facts as two equations ​

Answer 1

Answer:

Two equations are

3x + 5y = 169

5x + 3y = 159

Step-by-step explanation:

Let the 1st number be ' x '

Second number be ' y '

1st equation

3 times a number = 3x

5 times another number = 5y

Sum of both = 169

=> 3x + 5y = 169

2nd equation

5 times 1st number = 5x

3 times the second = 3y

Sum of both = 159

=> 5x + 3y = 159
