Solve the equation.<br><br> –3x + 1 + 10x = x + 4

SIZIF [17.4K]

First, simplify. Combine like terms

10x - 3x = 7x

7x + 1 = x + 4

Isolate the x. Subtract x from both sides, and 1 from both sides

7x (-x) + 1 (-1) = x (-x) + 4 (-1)

7x - x = 4 - 1

Simplify

6x = 3

Isolate the x. Divide 6 from both sides

6x/6 = 3/6

x = 1/2

1/2, or 0.5 is your answer for x.

Which polynomial correctly combines the like terms and expresses the given polynomial in standard form? 9xy3 â€"" 4y4 â€"" 10x2y

Aleksandr-060686 [28]

The first option is correct here: $-13y^4 + 3x^4 - 8x^2y^2 + x^3y + 9x y^3$

<h3>Given the polynomial:</h3>

$9xy^3 - 4y^4 - 10x^2y^2 + x^3y + 3x^4 + 2x^2y^2 - 9y^4$

<h3 /><h3>Simplification:</h3>

Combine the like terms together as shown below:

$9xy^3 - 4y^4 - 10x^2y^2 + x^3y + 3x^4 + 2x^2y^2 - 9y^4\\= (-4y^4 - 9y^4) + 9xy^3 + (-10x^2y^2 + 2x^2y^2) +x^3y +3x^4\\= -13y^4 +9xy^3 -8x^2y^2 + x^3y + 3x^4\\= -13y^4 +3x^4 -8x^2y^2 + x^3y + 9xy^3$

Thus, the first option is correct here: $-13y^4 + 3x^4 - 8x^2y^2 + x^3y + 9x y^3$
