Step-by-step explanation:
8a+12b= 92 ........ i
6a-4b=4 ............ ii
from eq ii
6a-4b= 4
6a= 4+4b
a= 4+4b÷6........iii
substituting the value of a in eq. I
8( 4+4b÷6) +12b = 92
16+ 16b ÷ 3+ 12b = 92
16+16b+ 36b = 276
52b= 260
b = 260÷52
b = 5
putting the value of b in eq. iii
a= 4+ 4×5 ÷6
a= 24÷6
a= 4
a= 4, b = 5
