a+2b-5c when a is equal to 2, b is equal to 3 and c is equal to 1.


Answer step by step.​

Answer 1

Answer:

Given,

5x - 3y

• If value of x is 2 , y is 5

: $\implies$ 5 × 2 - 3 × 5

: $\implies$ 10 - 15

: $\implies$ $\boxed{\sf{-5}}$

$\blue{\bold{\underline{\underline{}}}}$

a + 2b - 5c

• When a is 2 , b is 3 , c is 1

: $\implies$ 2 + 2 × 3 - 5 × 1

: $\implies$ 2 + 6 - 5

: $\implies$ 8 - 5

: $\implies$ $\boxed{\sf{3}}$
