inysia [295]
\left \{ {{7*x - 3*y=25} \atop {2*x + 5*y=95}} \right.

\left \{ {{7x - 3y=25}(I) \atop {2x + 5y=95}(II)} \right.

\left \{ {{7x - 3y=25}simplify*(5) \atop {2x + 5y=95}simplify*(3)} \right.

\left \{ {{35x - \diagup\!\!\!\! 15 y=125} \atop {6x + \diagup\!\!\!\! 15y=285}} \right.

\left \{ {{35x =125} \atop {6x =285}} \right.

41x = 410

\boxed{x=10}

<span>Replace the value of "x" in the second equation (II) to find the value of "y", thus:
</span>2x + 5y=95
2*(10)+5y = 95
20+5y=95
5y=95-20
5y=75
y =  \frac{75}{5}
\boxed{y=15}

xz_007 [3.2K]

Answer 813.8

Step-by-step explanation:

Well 813.8 is the answer. Why? Lets talk it out if there are 75 submissions and it says Paul will accept 2/5 of the submissions so we have to do is 75- 2/5 will be 74.6 and multiply by 13 because 13 pages is in a article so we got 969.8 and then minus 156 because it asking us how many "more" pages they need so 813.8 is the answer if you subtract 969.8 and 156.
