4y - x = 5 + 2y ..... (1)
3x + 7y = 24 ..... (2)
by grouping like terms in (1)
4y - x = 5 + 2y
4y - 2y - x = 5
<span>-x + 2y = 5 </span> ..... (1a)
by multiplying (1a) through by -3
(-3)(-x) + 2(-3)y = 5(-3)
3x - 6y = -15 ..... (1b)
by subtracting 1a from 2
3x -3x + 7y - (-6y) = 24 - (-15)
13y = 39
⇒ y = 3
by substituting y=3 into (2)
3x + 7(3) = 24
3x = 24 - 21
3x = 3
⇒ x = 1
∴ solution to the system is x=1 when y = 3
P = 4d +dgt
dgt = P -4d
divide both sides by dt.
g = (P-4d)/dt
Show how you got your answer in reverse. For example... if ur question is
4+4/(?)=4
8/?=4
oh its commen sense that the answer is 2.
now show how u got the answer 2.
? is 2 because, 4 times 2 equals 8
4(2)=8
Answer:
60%
Step-by-step explanation:
100%-40%-60%
if x=10 y=-2 and z=-5 then...
we solve this to get...
<em>65</em>
therefore the answer to your question would be 65
hope this helped-have a good day bro cya)
