Answer:
(1, -1)
Step-by-step explanation:
we isolate y in the first equation
2x+y=1
-2x. -2x
y=1-2x
and now we fill y into second equation
4x-2(1-2x)=6
4x-2+4x=6
8x-2=6
+2 +2
8x=8
/8 /8
x=1
and now to find y we insert x
2(1)+y=1
2+y=1
-2. -2
y= -1
hopes this helps
Step-by-step explanation:
You have to have tracing paper or patty paper (cause that's what my teacher uses). Next you draw the figure along with the x and y-axis on it as well. Then you mark the x and y-axis and rotate the paper 90 degrees clockwise. Lastly if the x-axis is on the y-axis, mark it as the y-axis and if the y-axis is on the x-axis, also mark it as the x-axis.
I hope this helped :)
The computation shows that the number of pages is 320.
The number of pages read in this second day will be 120.
<h3>How to illustrate the information?</h3>
Fraction read on first day = 1/4
Fraction news on second day = 1/2 × 3/4 = 3/8
Fraction read on last day = 1 - (1/4 + 3/8) =3/8
The number of pages that the book has will be:
= 3/8 × x = 120
0.375x = 120
x = 120/0.375
x = 320
The number of pages is 320.
b. The number of pages read on this second day will be:
= 3/8 × 320
= 120
