-2x + 7y = 10 ⇒ -2x + 7y = 10
x - 3y = -3 ⇒ <u>-2x + 6y = 6 </u>
y = 4
-2x + 7(4) = 10
-2x + 28 = 10
<u> -28 -28</u>
<u>-2x</u> = <u>-18</u>
-2 -2
x = 9
(x, y) = (9, 4)
7∛c*3∛(c⁴)- if you need only to rewrite
if you need to simplify, it can be made 2 ways
1)7∛c*3∛(c⁴) = 7∛c*3c∛(c)=21c∛(c²)
2) 7*3*c(^1/3)c(^4/3)=21c(^5/3)=21c(^1 2/3)=21c∛(c²)
59 is the first answer you are looking for and
I believe it is the first one
