Answer:

8

Step-by-step explanation:

Even though we don't know the number yet, let's name this number "n".

8n + 3 = 6n + 19

8n + 3 - 6n = 6n + 19 - 6n

2n + 3 = 19

2n = 16

n = 16/2

n = 8

Our number is 8.

Note: This answer is 100% correct.

and TS=TQ, so 3(x) + 2 = 3(4.5) + 2 = 13.5 + 2 = 15.5 =TQ

Please help me solve -6 = 14 - z/3

Solve. -6 = 14 - z/3Subtract 14 from both sides

-20 = -z/3

Multiply -3 by both sides to get rid of the negative and 3 with the z.

z= 60
