t=3

Explanation:

Begin by subtracting four from both sides:

15t+cancel(4-4)=49-4

15t=45

Now we divide both sides by 15 to isolate t:

(cancel15t)/cancel15=45/15

t=3

t=3

Explanation:

To solve an equation, we always want the x or t on its own. Therefore we -4 from both sides to cancel out the +4 on the side with t.

15t+4=49 -> 15t=45

as 49-4=45, it changes to 45

Now to solve an equation like this we divide the value, by how much of the x, t or another unknown value.

therefore t=45/15=3
