Reorganize the equations;
y -2x = -3.5
-2y+x = -14
Multiplying equation II by 2
y-2x = -3.5
-4y+2x= -28
----------------
-3y=24.5
y=

y= -8.17
Replacing value of y in equation 2;
-2(-8.17)-2x=-3.5
16.34-2x=-3.5
16.34+3.5=2x
19.84=2x
x=9.92
754/145 = 5.2
5.2 x 100 = 520
Final answer = 520
12.....because there are 4 quarters in $1
Answer:
6x^2 -2x
Step-by-step explanation:
As written, the constant terms in the first factor cancel each other. The distributive property is used to perform the multiplication:
(3x^2 +1 -1 -x)(2) = (3x^2 -x)(2) = (3x^2)(2) -x(2)
= 6x^2 -2x
