Simplifying
8t + 11 = 7t + -6
Reorder the terms:
11 + 8t = 7t + -6
Reorder the terms:
11 + 8t = -6 + 7t
Solving
11 + 8t = -6 + 7t
Solving for variable 't'.
Move all terms containing t to the left, all other terms to the right.
Add '-7t' to each side of the equation.
11 + 8t + -7t = -6 + 7t + -7t
Combine like terms: 8t + -7t = 1t
11 + 1t = -6 + 7t + -7t
Combine like terms: 7t + -7t = 0
11 + 1t = -6 + 0
11 + 1t = -6
Add '-11' to each side of the equation.
11 + -11 + 1t = -6 + -11
Combine like terms: 11 + -11 = 0
0 + 1t = -6 + -11
1t = -6 + -11
Combine like terms: -6 + -11 = -17
1t = -17
Divide each side by '1'.
t = -17
Simplifying
t = -17

8t + 11 = 7t - 6
8t + 11 - 7t = 7t - 6 - 7t
t + 11 = - 6
t + 11 - 11 = - 6 - 11
t = - 17
The answer is t = - 17

8t+11=7t-6
- 11 -11
-------------------
8t+0=7t-17
8t=7t-17
-7t -7t
1t=-17
t= -17
