Hey there! :)
Answer:
Choice C: x + 8 = 3x.
Step-by-step explanation:
Solve this question by simplifying each answer choice:
a) 4x = 20
Divide both sides by 4:
4x/4 = 20/4
x = 5. This is incorrect.
b) x/2 = 8
Multiply both sides by 2:
x = 16. This is incorrect.
c) x + 8 = 3x
Subtract x from both sides:
8 = 2x
Divide 2 from both sides:
x = 4. This is correct.
d) x = x+5 /2
Multiply both sides by 2:
2x = x + 5
Subtract x from both sides:
x = 5. This is incorrect.
Therefore, choice C is the correct answer.
Answer:
x=5
Step-by-step explanation:
3(2x-5) =15
6x-15=15
6x=15+15
6x= 30
6x/6=30/6
x=5
Would it be y=2x? because 2x= 14 which is also y
