1.4-1.6(t+6)=4.5

Solution for 1.4-1.6(t+6)=4.5 equation:

Simplifying
1.4 + -1.6(t + 6) = 4.5

Reorder the terms:
1.4 + -1.6(6 + t) = 4.5
1.4 + (6 * -1.6 + t * -1.6) = 4.5
1.4 + (-9.6 + -1.6t) = 4.5

Combine like terms: 1.4 + -9.6 = -8.2
-8.2 + -1.6t = 4.5

Solving
-8.2 + -1.6t = 4.5

Solving for variable 't'.

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

Add '8.2' to each side of the equation.
-8.2 + 8.2 + -1.6t = 4.5 + 8.2

Combine like terms: -8.2 + 8.2 = 0.0
0.0 + -1.6t = 4.5 + 8.2
-1.6t = 4.5 + 8.2

Combine like terms: 4.5 + 8.2 = 12.7
-1.6t = 12.7

Divide each side by '-1.6'.
t = -7.9375

Simplifying
t = -7.9375
