-2=d

2) 12=3/4y

4/3(12)=y

16=y

3) 4/5t+7=47

4/5t=40

t=40(5/4)

t=50

4) 15x+14=19

15x=5

x=5/15=1/3

2) 12=3/4y so 48 = 3/y so y/3 = 1/48 and y = 3/48 =1/16

3) 4/5t + 7 = 40 4/5t =40 t = 5/4 * 40 = 50

4) 15x + 14 = 19 15x = 5 x= 5/15 = 1/3

12=-6d 48y=3 235t+329=4

d=-2 y=1 over 16 235t=-325

t= -65over47

4)15x+14=19

15x=5

x=1over3

add the 1 to the 11 to get:

12= -6d

12/-6= -2

I know i’m not good at explaining but go talk 2 your teacher or look over your notes, or the book.

so you add one

12= -6d , then divde by -6

thus, d= -2

you get the idea!

All the best.
