Question

How do I solve the equation 9+t/12=-3?

Answer 1

Answer:

$\Huge\boxed{\mathsf{\Rightarrow T=-144}}$

Step-by-step explanation:

$\Large\boxed{\textnormal{SUBJECT: MATH}}}$

TO SOLVE:

Isolate by the t on one side of the equation.

SOLUTIONS:

First, subtract 9 from both sides.

$\displaystyle \mathsf{9+\frac{t}{12}-9=-3-9 }$

Solve.

$\displaystyle \mathsf{\Rightarrow \frac{t}{12}=-12 }$

Then, multiply by 12 from both sides.

$\displaystyle \mathsf{\frac{12t}{12}=12(-12) }}$

Solve.

Multiply.

$\displaystyle \mathsf{12*(-12)=\boxed{\mathsf{\rightarrow -144}}}$

$\Rightarrow \Large\boxed{\mathsf{T=-144}}$

The correct answer is t=-144.

Answer 2

Answer:

t=-144

Step-by-step explanation:

t in (-oo:+oo)

t/12+9 = -3 // + 3

t/12+3+9 = 0

1/12*t+12 = 0 // - 12

1/12*t = -12 // : 1/12

t = -12/1/12

t = -144

t = -144
