Hello there! the answer would be x = 3/4.
You are given the two equations: 4x - 2y = 8 and y = 1/2x + 2. You are asked to solve via substitution. To do this, substitute the value of y in the second given equation into the first given equation, and solve using PEMDAS.
4x - 2(1/2x + 2) = 8 - Start by distributing 2 into (1/2x + 2).
4x - 1x + 4 = 8 - Combine like terms.
3x + 4 = 8 - Subtract 4 from both sides.
3x = 4 - divide both sides by 3.
x = 3/4. This is your final answer.
I hope this was helpful, have a great day! :)
Answer:
0.25
Step-by-step explanation:
It should just be 2x-5= 125
Then add 5 to both sides
2x= 130
Divide by 2
X= 65
Take the logarithm of both sides
x =
(3)x +
(3)
Move expression
x-
(3)x =
(3)
Factor out x
x(1-
(3)) =
(3)
Divide
x = (
(3)) / (1-
(3))
