Question

3(t+4)=9 t=?
-(c-6)=0 c=?
-10(s+4)=-122 s=?​

Answer 1

t = -1

c = 6

s = 8.2 or 8 1/5 (same thing just different notation)

Explanation:

3(t+4) = 9

3t + 12 = 9

3t = -3

t = -1

-(c-6) = 0

-c + 6 = 0

-c = -6

c = 6

-10(s+4) = -122

-10s - 40 = -122

-10s = -82

10s = 82

s = 82/10 = 8.2 or 8 2/10 or 8 1/5
