Question

The sum of two numbers is 20 and their difference is 4. Frame the simultaneous equation.
Solve the following simultaneous equation -​

Answer 1

Answer:

bigger number = 12

smaller number = 8

Step-by-step explanation:

let the bigger number is X

smaller number = x - 4 ( thier difference is 4 )

so, x + ( x - 4 ) = 20

x + x - 4 = 20

2x - 4 = 20

2x = 20 + 4

2x = 24

x = 24 ÷ 2

x = 12

smaller number = 12 - y = 4

= -y = 4 - 12

= -y = -8

= y = 8
