What is the value of x in the equation 7x + 2y = 48 , when y = 3?<br><br> x =
Dennis_Churaev [7]
Plug in 3 for "y":

7x + 2y = 48

7x + 2(3) = 48

2*3 = 6

7x + 6 = 48 
Then, you have to subtract 6 to both sides..

7x = 42

Divide 7 to both sides and the your answer would be 6

What is the sum of the polynomials?
vivado [14]

The answer is 3x^2 + 6x + 4 (the second one)

Let's start by removing the parenthesis to get 6x + 7 + x^2 + 2x^2 - 3

Then, let's combine like terms (terms with the same variable and exponent) to get 3x^2 + 6x + 4

This is an answer in the multiple choice, so the answer is 3x^2 + 6x + 4 (the second one)
