Question

Two numbers have a sum of 1,212 and a difference of 518. Which system of equations could we use to solve this problem?

Answer 1

X+y =1212
x-y = 518
..............

Answer 2

Answer:

Answer is:

x + y = 1,212

x - y = 518

Step-by-step explanation:

Given that the sum of two numbers is 1,212 and their difference is 518,

To get system of equations we could use to solve this problem, we assume the two number to be x and y.

i.e first number to be x, second number to be y.

Therefore:

Two numbers have a sum of 1,212 will be expressed as x + y = 1212

While, difference of 518 will be expressed as x - y = 518

Therefore:

x + y = 1,212

x - y = 518
