Step-by-step EXPLANATION:

(I) 7x-3x+4

putting VALUES x=12 and y=3

=12×7-3×3+4

=84-9+4

=79

(ii) 8a÷4b

putting values a=2,b=2

=8×2÷4×2

=16÷8

(iii) -3p-r+4q

putting values p=2,r=4,q=-2

=-6-3-8

=-9-8

=-17

(iv) 9l-4m+3n

putting values l=2,m=4,m=5

=18-16+15

=2+15

=17

I hope it helps U
