Given,
9(x+1) = 25 + x
expanding,
9x + 1 = 25 + x
bringing x to left hand side and taking 1 to right hand side with change in their respective signs,
9x - x = 25-1
=> 8x = 24
transposing 8 ,
=> x = 24/8 = 3
Hence x = 3
Answer:
The solution is (0, 3/4)
Step-by-step explanation:
Please copy and share the instructions. Here they are: Solve the following system of linear equations.
Both of the equations can be reduced (simplified):
2x+8y = 6 => x + 4y = 3
15x + 20y = 15 => 3x + 4y = 3
Let's use the elimination by addition and subtraction method. Multiply the first equation by -1, obtaining
-x - 4y = -3
Add the second 3x + 4y = 3
equation to the
first.
We get: 2x = 0.
Thus, x = 0. Substituting 0 for x in the 1st original equation yields:
2(0) + 8y = 6. Then y = 6/8, or y = 3/4.
The solution is (0, 3/4).
Answer: x=2 and y=−6
Step-by-step explanation: 2x+y=−2, 5x+3y=−8
2x+y=−2
2x+y+−2x=−2+−2x
y=−2x−2
5x+3y=−8
5x+3(−2x−2)=−8
−x−6+6=−8+6
−x=−2
−x

/−1
x=2
y=−2x−2
y=(−2)(2)−2
y=−6
x=2 and y=−6
Answer:
B. 5
Hope it helps!
Step-by-step explanation:
It lists green 5 times.
Im not sure about this one but it could be 12x+75y+21 and b+3+6c / disclaimer may be wrong. have a good day!
