Answer:

Step-by-step explanation:

1/5 x^2y - 1 2/3 y^2 x + 4 4/5 yx^2 - 1/3 xy^2

I will write the x and y terms in order for x and y

1/5 x^2y - 1 2/3 xy^2 + 4 4/5 x^2y - 1/3 xy^2

This way I can put the like terms together

1/5 x^2y + 4 4/5 x^2y- 1 2/3 xy^2 - 1/3 xy^2

Combine like terms

(1/5 + 4 4/5) x^2y - (1 2/3 + 1/3) xy^2

5 x^2 y - 2 xy^2

We know x =-2 and y = 1/2

5 ( -2)^2 (1/2) -2(-2) (1/2)^2

Calculating the powers first

5(4) (1/2) - 2(-2) (1/4)

Solve the equation. 8 – 2x = –8x + 14

goldenfox [79]

Answer:

$x=1$

Step-by-step explanation:

We are asked to solve the given equation: $8-2x=-8x+14$ .

To solve this equation we will combine like terms by moving all the terms containing x to the left hand side of equation and terms without x to right hand side of equation.

Let us add 8x to both sides of our equation.

$8-2x+8x=-8x+8x+14$
