<span>x – y = 30, when y = 15
x - 15 = 30
x = 30 + 15
x = 45
answer: </span><span>when y = 15, x = 45</span>
Answer:
<u>x = 3</u>
Step-by-step explanation:
y = 5x
x + y = 12
x + 5x = 12 (substitute 5x in the place of y)
6x = 12
x = 12/6
<u>x = 3</u>
X^3= 343
Find the cube root of both sides
∛x^3 = ∛343
x= 7
Final answer: x=7
