We have such system of eq
First lets solve second eq
7x=21 /:7 divide both sides by 7
x=3
Now we can substitute it to first equation
9x-2y=19
9*3-2y=19
27-2y=19 /-27 subtract 27 both sides
-2y=-8 /:(-2) divide both sides by -2
y=4 - its the answer
H because it doesn’t go in a straight line
Answer
It would be basically 25
Step-by-step explanation:
there is no picture but it would be probably 5x5=25
Your answer is <em>infinitely</em><em> </em><em>many</em><em> </em><em>solutions</em><em> </em>
Step-by-step explanation:
-4x+-20=-4x-20
+4× +4x
(4x cancel out)
Your left with
-20=-20
Therefore your answer is infinitely many solutions
<u>QUESTION :</u>
Find the given value of each angle for the following supplementary angles must add up to 180
- one angle = (5x-13)°
- another angle = (11x+65)°
➱<em>ᴛʜᴇ ᴛᴡᴏ ᴀɴɢʟᴇs ʟɪᴇs ᴏɴ ᴛʜᴇ sᴀᴍᴇ ʟɪɴᴇ</em>
➱ѕσ ѕυм σƒ вσтн тнє αηgℓєѕ = 180°
therefore ,
⤳(5x-13)° + (11x+65)° = 180°
⤳5x -13° + 11x + 65° = 180°
⤳16x + 52° = 180°
⤳16x = 180° - 52°
⤳16x = 128°
⤳x = 128 /16
hence ,
the two angles will be
⇛<u>ᴏɴᴇ ᴀɴɢʟᴇ</u> :
<em>➛</em>(5x-13)°
<em>➛</em>5(8) - 13
<em>➛</em>40 - 13
⇛<u>ᴀɴᴏᴛʜᴇʀ ᴀɴɢʟᴇ</u> :
<em>➛</em><em> </em>(11x+65)°
<em>➛</em>11(8)+65
<em>➛</em>88 + 65
