-3/4x>12 solve for x​
Ad libitum [116K]

Answer:

\Huge\boxed{\mathsf{\rightarrow X

Step-by-step explanation:

\Large\boxed{\mathsf{SUBJECT: MATH}}

Isolate x on one side of the equation.

Find the value of x.

First, multiply -1 from both sides.

(-3/4x)(-1)<12(-1)

Solve.

12(-1)=-12

3/4x<-12

Next, multiply 4 from both sides.

4*3/4x<4(-12)

Solve.

Multiply the numbers from left to right.

4(-12)=-48

3x<-48

Then, divide by 3 from both sides.

3x/3<-48/3

Solve.

Divide the numbers from left to right.

-48/3=-16

X<-16

\Large\boxed{\Rightarrow \mathsf{X

The correct answer is x<-16.
