-3 + 4t = 3(1 + 3t)
-3 + 4t = (1 * 3 + 3t * 3)
-3 + 4t = (3 + 9t)

Solving
-3 + 4t = 3 + 9t

Solving for variable 't'.

Move all terms containing t to the left, all other terms to the right.

Add '-9t' to each side of the equation.
-3 + 4t + -9t = 3 + 9t + -9t

Combine like terms: 4t + -9t = -5t
-3 + -5t = 3 + 9t + -9t

Combine like terms: 9t + -9t = 0
-3 + -5t = 3 + 0
-3 + -5t = 3

Add '3' to each side of the equation.
-3 + 3 + -5t = 3 + 3

Combine like terms: -3 + 3 = 0
0 + -5t = 3 + 3
-5t = 3 + 3

Combine like terms: 3 + 3 = 6
-5t = 6

Divide each side by '-5'.
t = -1.2

Simplifying
t = -1.2
