Question

Evaluate 3+11t−9u when t=9 u=11

Answer 1

Answer:

Simplifying

3 + 11t + -9u = 0

Solving

3 + 11t + -9u = 0

Solving for variable 't'.

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

Add '-3' to each side of the equation.

3 + 11t + -3 + -9u = 0 + -3

Reorder the terms:

3 + -3 + 11t + -9u = 0 + -3

Combine like terms: 3 + -3 = 0

0 + 11t + -9u = 0 + -3

11t + -9u = 0 + -3

Combine like terms: 0 + -3 = -3

11t + -9u = -3

Add '9u' to each side of the equation.

11t + -9u + 9u = -3 + 9u

Combine like terms: -9u + 9u = 0

11t + 0 = -3 + 9u

11t = -3 + 9u

Divide each side by '11'.

t = -0.2727272727 + 0.8181818182u

Simplifying

t = -0.2727272727 + 0.818181818
