.3(t-2)=0.4t

Solution for .3(t-2)=0.4t equation:

Simplifying
0.3(t + -2) = 0.4t

Reorder the terms:
0.3(-2 + t) = 0.4t
(-2 * 0.3 + t * 0.3) = 0.4t
(-0.6 + 0.3t) = 0.4t

Solving
-0.6 + 0.3t = 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.
-0.6 + 0.3t + -0.4t = 0.4t + -0.4t

Combine like terms: 0.3t + -0.4t = -0.1t
-0.6 + -0.1t = 0.4t + -0.4t

Combine like terms: 0.4t + -0.4t = 0.0
-0.6 + -0.1t = 0.0

Add '0.6' to each side of the equation.
-0.6 + 0.6 + -0.1t = 0.0 + 0.6

Combine like terms: -0.6 + 0.6 = 0.0
0.0 + -0.1t = 0.0 + 0.6
-0.1t = 0.0 + 0.6

Combine like terms: 0.0 + 0.6 = 0.6
-0.1t = 0.6

Divide each side by '-0.1'.
t = -6

Simplifying
t = -6
