I don't know exactly what answer you're looking for but that's what I got. This shouldn't have been hard to pick up on in class lol.
The first one. Substitute both $82 and $42 to get the 4 and 9 hundreds.
Y = -1/8*82+57/4 = 4 hundreds
1/((R2+R1)/(R2*R1))
= 1/(R2+R1) * (R2*R1)/1
So answer 4
b = i+12
b-3 = 4( i-3) ------> b-3=4i-12 ----->b=4i-9
b = i+12
b=4i-9
i+12=4i-9
21=3i
i=7
b= i+12
b=7+12=19 Ben is 19 years old now
