To solve for 2 variables, you need 2 equations. The best you could do with only one equation would be to find 'a' in terms of 'b'. Just looking it over and without putting pen to paper, it looks to me like one possible solution is [ a = 4, b = 0 ].

The difference between two numbers is 2790. If the smaller number is 3560, what is the other number?
8090 [49]

Answer:

the other number is 6350

Step-by-step explanation:

given data

difference between two numbers = 2790

smaller number = 3560

to find out

the other number

solution

we consider here larger number  = x

smaller number  = y

so

so difference between two number is express as

difference between two number = x - y    ....................1

put here value and we get another number i.e large number

2790 = x - 3560

solve it we get

x = 6350

so the other number is 6350
