Answer:

6y-(4y-12)=20

-bring down 6y

-multiply -x (-1) by 4y

-multiply -x by 4y

-6y -4+12=20

- combine -4 and positive 12

- 6y+8=20

-subtract 8 from both sides

- 6y=12

- divide both sides by 6

y= 2

Answer:

y = 4

Step-by-step explanation:

6y - (4y - 12) = 20

Distribute;

6y - 4y + 12 = 20

2y + 12 = 20

Subtract 12 from both sides;

2y = 8

Divide both sides by 2;

y = 4

BRAINLIEST FOR RIGHT ANSWER!!

Answer: ${\boxed{h(x+4)=\frac{9+3x}{8+x}}}$

Concept:

In a function f(x), it represents a function in terms of x or for x. Therefore, to find the values in the function, substitute values within the parenthesis to solve.

Solve:

Given information

$h(x)=\frac{-3+3x}{4+x}$

Need to find

$h(x+4)$

Substitute (x + 4) to the position of x

$h(x+4)=\frac{-3+3(x+4)}{4+(x+4)}$

Distributive property on the numerator

$h(x+4)=\frac{-3+3x+12}{4+(x+4)}$

Combine like terms

$h(x+4)=\frac{-3+12+3x}{4+4+x}$

$\boxed{h(x+4)=\frac{9+3x}{8+x}}$

Hope this helps!! :)

How can i add the fractions using a giant one to create a conmon 1 denominator /4+5/8

Mice21 [21]

Stack them on top of each other and find the common denominator then multiply to total the denominator. Ex. 1/4 denominator is 8. 4x2 is 8. So 1 times what equals 8. 1! Then you should a new fraction 8/8 which is equivalent to 1.
