Question

Solve the problem 3x+5y=15

Answer 1

Step-by-step explanation:

let x = o

3×0 + 5y = 15

y = 15/5 = 3

let y = 0

3x + 5×0 = 15

x = 15/3 = 5

HOPE THIS HELP YOU.

Answer 2

Answer:

Given: 3x+5y =15

we can write this as 5y =15÷3x

Let x = 1

then, we can write --

5y = 15÷3×1

=15÷3

=5

then, 5y=5

y=5÷5=1

Y =1

Now, we can put the value of y in

5y =15 ÷3x

5×1=15÷3x

5= 15÷3x

5×3x =15

15x = 15

X = 15÷15=1

Hope you understand.
