Answer:

x=-248 3/5

Step-by-step explanation:

13-9-x/11=3x/22+121/2

4-x/11=3x/22+121/2

4-121/2=3x/22+x/11

8/2-121/2=3x/22+2x/22

-113/2=5x/22

5x/22=-113/2

5x=(-113/2)*22

5x=-113*22/2

5x=-113*11

x=-1243/5

x=-248 3/5

Solve for g E=4gh How do you solve this equation

11111nata11111 [884]

Answer:

g = E/4h

Step-by-step explanation:

In order to solve for a variable, you have to isolate it from the other values on one side of the equation.

Because g is multiplied by 4 and h, undo this operation by dividing both sides of the equation by 4h.

$\frac{E}{4h} = \frac{4gh}{4h} \\\\ \frac{E}{4h} = g$
