Brainliest for correct awnser! ASAP! Use the guess check method! Teresa got a $25 gift card for her birthday. She can download an album for $9 and an individual song for $1. She spends all $25 to download 9 recordings. How many of each type did she download? A. 2 albums, 7 songs B. 1 album, 8 songs C. 4 albums, 5 songs D. 3 albums, 6 songs

Option A

Step-by-step explanation:

Let's denote:

x is the number of albums Teresa downloads.

y is the number of individual songs Teresa downloads.

=> 9x + y = 25

Let's check:

Option A: x = 2 and y = 7 => 9 x (2) + 7 = 18 + 7 = 25 => valid

Option B: x = 1 and y = 8 => 9 x (1) + 8 = 9 + 8 = 17 => invalid

Option C: x = 4 and y = 5 => 9 x (4) + 5 = 36 + 5 = 41 => invalid

Option D: x = 3 and y = 6 => 9 x (3) + 6 = 27 + 6 = 33 => invalid

starting with:    

5 + x - 12 = 2x - 7   

5 + x - 12 - x = 2x - 7 - x (subtract x from both sides)   

5 - 12 = x - 7 (combine and cancel x's from both sides)   

5 - 12 + 7 = x - 7 + 7 (add 7 to both sides)   

0 = x (add numbers together on both sides)       

so in order for the equation to be true, x must be 0.   

trying x = -0.5   

5 + x - 12 = 2x - 7 (original equation)   

5 + -0.5 - 12 = 2(-0.5) - 7 (plug in value of x)   

5 + -0.5 - 12 = -1 - 7 (did multiplication)   

-7.5 = -8 (did addition on both sides)       

since -7.5 is obviously not equal to -8, the value of -0.5 for x is wrong.   

trying x = 0   

5 + x - 12 = 2x - 7 (original equation)   

5 + 0 - 12 = 2(0) - 7 (plug in value of x)   

5 + 0 - 12 = 0 - 7 (did multiplication)   

-7 = -7 (did addition on both sides)       

since -7 equals -7, that demonstrates that the value of 0 for x is correct.   

trying x = 1   

5 + x - 12 = 2x - 7 (original equation)   

5 + 1 - 12 = 2(1) - 7 (plug in value of x)   

5 + 1 - 12 = 2 - 7 (did multiplication)   

-6 = -5 (did addition on both sides)       

since -6 is obviously not equal to -5, the value of 1 for x is wrong.

just pick what you think i need more time let me know if this
