I believe the answer is B. 39, 49, 59
Answer: c.) 4
Step-by-step explanation:
y = 4
Plug in 4 for y.
6(4 + 2) + 4 = 40
24 + 12 + 4 = 40
40 = 40
To prove that x = 2 in the equation given, first, we write the given.
(4) Given: (A) 12 - x = 20 - 5x
Then, add 5x to both sides of the equation,
(3) Addition property of equality: (B) 12 + 4x = 20
Then, subtract 12 from both sides of the equation
(2) Subtraction property of equality: (C) 4x = 8
Lastly, divide both sides by 4
(1) Division property of equality : (D) x = 2
Answer:
x = (8+y)/3
Step-by-step explanation:
3x-y=8
Add y to each side
3x-y+y=8+y
3x = 8+y
Divide each side by 3
3x/3 = (8+y)/3
x = (8+y)/3
