Step-by-step explanation:
making x subject in eq 1
x= (-1-9y)/-14
substituting the value of x in eq 2
17(-1-9y/-14)=7+9y
(-17-153y)/-14=7+9y
-17-153y=-98-126y
-17+98=153y-126y
81=27y
y=3
substituting this value of y in eq 1
-14x=-1-9(3)
-14x=-28
x=2
(x,y) = (2,3)
 
        
             
        
        
        
<span>Step 1:
</span>
<span> (((22•5x2) + 25x) - 12x) - 15)))
</span>
<span>The first term is, <span> <span>20x2</span> </span> its coefficient is <span> 20 </span>.
The middle term is, <span> +13x </span> its coefficient is <span> 13 </span>.
The last term, "the constant", is <span> -15 
</span></span>
<span>step 2 above,  -12  and  25 
                     <span>20x2 - 12x</span> + 25x - 15
Step-4 : Add up the first 2 terms, pulling out like factors :
                    4x • (5x-3)
              Add up the last 2 terms, pulling out common factors :
                    5 • (5x-3)
 Step-5 : Add up the four terms of step 4 :
                    (4x+5)  •  (5x-3)
             Which is the desired factorization</span>Final result :<span> (5x - 3) • (4x + 5)
</span>
