1.

2x + 14 = 14x - 82 add 82 to both sides

2x + 96 = 14x subtract 2x from both sides

96 = 12x divide both sides by 12

x = 8 answer

check

2(8) + 14 = 14(8) - 82

16 + 14 = 112 - 82

30 = 30

2) 7x^2 + 4x + 2 from -10x^2 + 4x - 3

(-10x^2 + 4x - 3) - (7x^2 + 4x + 2)

-10x^2 + 4x - 3 - 7x^2 -4x - 2

-17x^2 - 5 answer

3) -8x^5y^3(6x^4y)

-8*x^5 * y^3 *6 * x^4 * y

-8 * 6 * x^5 * x^4 * y^3 * y

-48 * x^9 * y^4

-48x^9y^4 answer

1. 96 =12x so x=9

2. 17x^2 + 8x -1

3. -48x^9y^4

Hope that helps
