725,278 * 67,066 = 48641494348....now, if x is in the 10 digits spot...it is 4...and if y is in the units spot, then it is 8.....
x + y = 4 + 8 = 12

X+2=x+10<br><br>I need to set them equal to each other. Please show workk​
soldi70 [24.7K]
These cannot be set equal to each other. you know this because of the following: x + 2 = 10 + x. subtract x from both sides to get 2 = 10, which is not true. they cannot be set equal to each other.

Which of these strategies would eliminate a variable in the system of equations?
Novosadov [1.4K]

Multiply the top equation by 6 and and the bottom equation by –5 and then add the equations is the correct answer.

Solution:

Given system of equations:

8x + 5y = –7 – – – – (1)

–7x + 6y = –4 – – – – (2)

Multiply top equation by 6 and and bottom equation by –5

(1) × 6 ⇒ 48x + 30y = –42

(2) × –5 ⇒ 35x – 30y = 20

Now add these two equations, we get

(48x + 30y) + (35x – 30y) = –42 + 20

48x + 35x + 30y  – 30y = –42 + 20

83x = –20

The variable y is eliminated.

Therefore Multiply the top equation by 6 and and the bottom equation by –5 and then add the equations is the correct answer.
