Question

let a=2x+y,b=5y+3 and c=x+2 find the value of a-b+c​

Answer 1

Given:

a = 2x+y

b = 5y+3

c = x+2

Find:

Value of a-b+c

Solution:

a-b+c = (2x+y) - (5y+3) + (x+2)

(2x+y) - (5y+3) + (x+2)

2x+y-5y-3+x+2

2x+x+y-5y-3+2

3x-4y-1

Final answer:

Therefore the value of a-b+c is 3x-4y-1.

Answer 2

Solution

Given,

• a = 2x+y
• b = 5y +3
• c = x +2

To find ,

• the value of a-b+c

Now,

we know that ;

a-b+c = (2x +4)-(5y+3)+(x+2)

by solving this we can get the answer

So,

$= > (2x + y) - (5y + 3) + (x + 2) \\ = > 2x + y - 5y - 3 + x + 2$

$= > 2x + x + y - 5y - 3 + 2 \\ = > \bold{3x - 4y - 1}$

So, the final result is :-

a-b + c = 3x -4y - 1
