1/2 - 3/11

Set both denominators (bottom numbers) to 22, so multiply the numerator of 1/2 by 11, and multiply the numerator of 3/11 by 2.

1/2 is now 11/22

3/11 is now 6/22

So, our new question is now : 11/22 - 6/22

Because the denominators are the same, all you have to do is simplify the top numbers.

So, 11-6 = 5

Therefore, your answer is 5/22

Describe two ways to solve the equation 2(4x-11)=10

shtirl [24]

2(4x-11) = 10

On dividing 2 on both sides

$\frac{2(4x-11)}{2} = \frac{10}{2}$

$4x-11 = 5$

On Adding 11 on both sides:

$4x-11+11 = 11+5$

$4x = 16$

On dividing both side by 4

$\frac{4x}{4} = \frac{16}{4}$

$x = 4$

Second way is:

We can use distributive property as

$2(4x-11) = 10$

$2*4x- 2*11 = 10$

$8x - 22 = 10$

On Adding 22 on both side

$8x - 22+22 = 10+22$

$8x = 32$

On dividing both side by 8

$\frac{8x}{8} = \frac{32}{8}$

$x = 4$

Solve for y: |6y - 3| + 8 = 35 Select one: a. y = -5 b. y = 5 or y = -4 c. =5=−203 y = 5 o r y = − 20 3 d. y = 5

SpyIntel [72]

Answer:

y=5 or y=-4

Step-by-step explanation:

6y - 3| + 8 = 35

|6y-3|=35-8

|6y-3|=27

either 6y-3=-27 then 6y=27+3

y=30/6=5

or 6y-3=-27

6y=-27+3

y=-24/6

y=-4

Solving linear systems of substitution

never [62]

Example: 2x+2y=8 and 3y+2x=6
Okay so u first want to put on of the equations into a y= form. So let's use 3y+2x=6. Subtract 2x from both sides. 3y=6-2x divide by 3. Y= 6-2/3x or y= -2/3x + 6. Now just plug this new equation in for Y since "y=" into the other equation.
2x + 2(-2/3x + 6) = 8.
Then you would distribute the 2 into the parenthesis and simplify to solve for x.
After you solve for x, plug x into one of the original equations to find y.
