0.65t+0.35(10-t)=0.39(10)

Solution for 0.65t+0.35(10-t)=0.39(10) equation:

Simplifying
0.65t + 0.35(10 + -1t) = 0.39(10)
0.65t + (10 * 0.35 + -1t * 0.35) = 0.39(10)
0.65t + (3.5 + -0.35t) = 0.39(10)

Reorder the terms:
3.5 + 0.65t + -0.35t = 0.39(10)

Combine like terms: 0.65t + -0.35t = 0.3t
3.5 + 0.3t = 0.39(10)

Multiply 0.39 * 10
3.5 + 0.3t = 3.9

Solving
3.5 + 0.3t = 3.9

Solving for variable 't'.

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

Add '-3.5' to each side of the equation.
3.5 + -3.5 + 0.3t = 3.9 + -3.5

Combine like terms: 3.5 + -3.5 = 0.0
0.0 + 0.3t = 3.9 + -3.5
0.3t = 3.9 + -3.5

Combine like terms: 3.9 + -3.5 = 0.4
0.3t = 0.4

Divide each side by '0.3'.
t = 1.333333333

Simplifying
t = 1.333333333
