Answer: y=  −3 /10 x +  2 /5

Step-by-step explanation:

Let's solve for y.

−3(x+y)+4=7y

Step 1: Add -7y to both sides.

−3x−3y+4+−7y=7y+−7y

−3x−10y+4=0

Step 2: Add 3x to both sides.

−3x−10y+4+3x=0+3x

−10y+4=3x

Step 3: Add -4 to both sides.

−10y+4+−4=3x+−4

−10y=3x−4

Step 4: Divide both sides by -10.

−10y /−10  =  3x−4 / −10

y=  −3 /10 x+  2 /5

Factories <br>(a+b)^3+8c^3​
Rom4ik [11]

Answer:

(a + b + 2c)(a² + 2ab + b² - 2ac - 2bc + 4c²)

Step-by-step explanation:

Given

(a + b)³ + 8c³ ← this is a sum of cubes and factors in general as

a³ + b³ = (a + b)(a² - ab + b²)

Thus

(a + b)³ + 8c³

= (a + b)³ + (2c)³

= (a + b + 2c)( (a + b)² - 2c(a + b) + (2c)² )

= (a + b + 2c)(a² + 2ab + b² - 2ac - 2bc + 4c²)
