Is t=3 a solution to the equation given below? *
2 X t - 8 = 7

             NO, it isn't

Step-by-step explanation:

To check it you just need to put 3 in place of t and if you get true equation then t=3 is a solution. If you get false then isn't.

2×t - 8 = 7

2×3 - 8 = 7

6 - 8 = 7

-2 ≠ 7       ⇒  t=3  is no solution

the 4th choice is the correct one

step-by-step explanation:

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
