Simplify: 8y - x + 11, when x = 2y - 3

6y + 14

Step-by-step explanation:

replace the x in the given expression with 2y - 3

8y - (2y - 3) + 11 ➡ 8y - 2y + 3 + 11 = 6y + 14

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,
