Answer:
Hiiiii
The answer is 4 + 2 + 7= 13
Sorry if it incorrect
Have a nice day
<span>X+2y=10 ----Eq.1
</span><span>x+y=6---------Eq.2
from Eq2.
x=6-y
Subtituting the value of X in the first equation
6-y+2y=10
6+y=10
y=4
Plug y=4 in equation 2.
</span><span>x+4=6
</span>X= 2
No,
5x means 5 is being multiplied by a number (x)
x+5 means that’s a number (x) is being added to 5
Hope this helps ;)
To find a perfect square we want the equation to look like (y - 8)(y-8) because
the two numbers that add up to -16 and multiply into 64. are -8, -8. -8^2 is 64.
