Answer:
Step-by-step explanation:
5x+3y=1
4x-5y=4
--------------
4(5x+3y)=4(1)
-5(4x-5y)=-5(4)
----------------------
20x+12y=4
-20x+25y=-20
----------------------
37y=-16
y=-16/37
5x+3(-16/37)=1
5x-48/37=1
5x=1+48/37
5x=37/37+48/37
5x=85/37
x=(85/37)/5
x=(85/37)(1/5)
x=85/185
x=17/37
Answer: x=17/37, y=-16/37. (17/37, -16/37)
-----------------------------
5x+3y=1
8x-10y=4
-----------------
8(5x+3y)=8(1)
-5(8x-10y)=-5(4)
----------------------
40x+24y=8
-40x+50y=-20
----------------------
75y=-12
y=-12/75=-4/25
5x+3(-4/25)=1
5x-12/25=1
5x=1+12/25
5x=25/25+12/25
5x=37/25
x=(37/25)/5
x=(37/25)(1/5)
x=37/125
Answer: x=37/125, y=-4/25. (37/125, -4/25).
-------------------------------
5x+3y=1
9x-2y=5
---------------
2(5x+3y)=2(1)
3(9x-2y)=3(5)
---------------------
10x+6y=2
27x-6y=15
---------------
37x=17
x=17/37
5(17/37)+3y=1
85/37+3y=1
3y=1-85/37
3y=37/37-85/37
3y=-48/37
y=(-48/37)/3
y=(-48/37)(1/3)
y=-48/111
Answer: x=17/37, y=-48/111. (17/37, -48/111).

<h3><u>The value of the unknown number is equal to 1.</u></h3>
6(x + 2) = 20x - 2
Distributive property.
6x + 12 = 20x - 2
Subtract 6x from both sides.
12 = 14x - 2
Add 2 to both sides.
14 = 14x
Divide both sides by 14.
x = 1
<span><span>Corresponding angles are congruent (same measure)So in the figure above, the angle P=P', Q=Q', and R=R'.</span><span>Corresponding sides are all in the same proportionAbove, PQ is twice the length of P'Q'. Therefore, the other pairs of sides are also in that proportion. PR is twice P'R' and RQ is twice R'Q'.
so the value of x :
x / 110 = 21.6 / 72
solve for x
x = 33</span></span>
It means 1*10^+a number
for example:
1e*10^+11
the +11 is an exponent but with a plus sign
furthering the answer you'll get: 100000000000
<span>The first 4 is in the hundreds value = 400 and the second is in the tens value = 40. When you break down the three digit number into hundreds value, tens value, and no value you will find that it is made up of 400 + 40 + 0 = 440.</span>
