0.39(t-2)=0.4t

Solution for 0.39(t-2)=0.4t equation:

Simplifying
0.39(t + -2) = 0.4t

Reorder the terms:
0.39(-2 + t) = 0.4t
(-2 * 0.39 + t * 0.39) = 0.4t
(-0.78 + 0.39t) = 0.4t

Solving
-0.78 + 0.39t = 0.4t

Solving for variable 't'.

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

Add '-0.4t' to each side of the equation.
-0.78 + 0.39t + -0.4t = 0.4t + -0.4t

Combine like terms: 0.39t + -0.4t = -0.01t
-0.78 + -0.01t = 0.4t + -0.4t

Combine like terms: 0.4t + -0.4t = 0.0
-0.78 + -0.01t = 0.0

Add '0.78' to each side of the equation.
-0.78 + 0.78 + -0.01t = 0.0 + 0.78

Combine like terms: -0.78 + 0.78 = 0.00
0.00 + -0.01t = 0.0 + 0.78
-0.01t = 0.0 + 0.78

Combine like terms: 0.0 + 0.78 = 0.78
-0.01t = 0.78

Divide each side by '-0.01'.
t = -78

Simplifying
t = -78
