(-9*-9)=(2*2)t+(3*6+1)t

Solution for (-9*-9)=(2*2)t+(3*6+1)t equation:

Simplifying
(-9 * -9) = (2 * 2) * t + (3 * 6 + 1) * t

Multiply -9 * -9
(81) = (2 * 2) * t + (3 * 6 + 1) * t
81 = (2 * 2) * t + (3 * 6 + 1) * t

Multiply 2 * 2
81 = (4) * t + (3 * 6 + 1) * t

Multiply 3 * 6
81 = 4t + (18 + 1) * t

Combine like terms: 18 + 1 = 19
81 = 4t + (19) * t

Combine like terms: 4t + 19t = 23t
81 = 23t

Solving
81 = 23t

Solving for variable 't'.

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

Add '-23t' to each side of the equation.
81 + -23t = 23t + -23t

Combine like terms: 23t + -23t = 0
81 + -23t = 0

Add '-81' to each side of the equation.
81 + -81 + -23t = 0 + -81

Combine like terms: 81 + -81 = 0
0 + -23t = 0 + -81
-23t = 0 + -81

Combine like terms: 0 + -81 = -81
-23t = -81

Divide each side by '-23'.
t = 3.52173913

Simplifying
t = 3.52173913
