Question

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

Answer 1

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

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+(t)/(12)-9=-3-9 }`

Solve.

`\displaystyle \mathsf{\Rightarrow (t)/(12)=-12 }`

Then, multiply by 12 from both sides.

`\displaystyle \mathsf{(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

t=-144

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
