Simplify 3(7t-5) - 2t = 4​

t =1

Step-by-step explanation:

3(7t-5) - 2t = 4​

21t-15-2t=4

19t-15=4

+15

19t=19

/19

t=1

hopes it helps!!!.

Step-by-step explanation:

3(7t - 5) - 2t = 4

3*7t - 3*5 - 2t = 4

21t  - 15   - 2t = 4          {combine like terms}

21t - 2t - 15     = 4

         19t - 15 = 4          {Add  15 to both sides}

            19t    = 4 + 15

            19t     = 19    {Divide both sides by 19}

                   t = 19/19

t = 1

a=-3456

b=-21/36

Step-by-step explanation:

(7/b)-36=(28/b)

(7/b)-(28/b)=36

7-28=36b

-21=36b

-21/36=b

Since you found one variable substitute it in to find the other variable

28/b=a/72

28/(-21/36)=a/72

28 * (36/-21)=a/72

-48=a/72

72* -48 = a

a=-3456

a=-3456

b=-21/36
