Step-by-step explanation:

7a -5b+3c. =7 (1)-5 (2)+3 (3). =7-10+9. =6. 2a-b+c. =2 (1)- 2+3. =2-2+3. =3. 3a+2b. =3 (1)+2 (2). =3+4. =7.

Answer 2

Answer:

Your answers along with the process is given below.

Step-by-step explanation:

3a+2b ; 2a-b+c ; 7a-5b+3c​ when a=1,b=2,c=3

Starting with the first equation, we have:

3a + 2b

= (3 x 1) + (2 x 2)

= 3 + 4

= 7 (answer)

For the second equation, we have:

2a - b + c

= (2 x 1) - 2 + 3

= 2 - 2 = 3

= 0 + 3

= 3 (answer)

And finally, For the third equation, we have:

7a - 5b + 3c

= (7 x 1) - (5 x 2) + (3 x 3)

= 7 - 10 + 9

= (-3) + 9

= 6 (answer)

Hope it helps you!
