-(2t-.71)=.9(1.4-t)

Solution for -(2t-.71)=.9(1.4-t) equation:

Simplifying
-1(2t + -0.71) = 0.9(1.4 + -1t)

Reorder the terms:
-1(-0.71 + 2t) = 0.9(1.4 + -1t)
(-0.71 * -1 + 2t * -1) = 0.9(1.4 + -1t)
(0.71 + -2t) = 0.9(1.4 + -1t)
0.71 + -2t = (1.4 * 0.9 + -1t * 0.9)
0.71 + -2t = (1.26 + -0.9t)

Solving
0.71 + -2t = 1.26 + -0.9t

Solving for variable 't'.

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

Add '0.9t' to each side of the equation.
0.71 + -2t + 0.9t = 1.26 + -0.9t + 0.9t

Combine like terms: -2t + 0.9t = -1.1t
0.71 + -1.1t = 1.26 + -0.9t + 0.9t

Combine like terms: -0.9t + 0.9t = 0.0
0.71 + -1.1t = 1.26 + 0.0
0.71 + -1.1t = 1.26

Add '-0.71' to each side of the equation.
0.71 + -0.71 + -1.1t = 1.26 + -0.71

Combine like terms: 0.71 + -0.71 = 0.00
0.00 + -1.1t = 1.26 + -0.71
-1.1t = 1.26 + -0.71

Combine like terms: 1.26 + -0.71 = 0.55
-1.1t = 0.55

Divide each side by '-1.1'.
t = -0.5

Simplifying
t = -0.5
