Hello
-4x + 11y = 15
x = 2y
Ok, we need to solve x = 2y for x
Lets start by substitute 2y for x in -4x + 11y = 15
-4x + 11y = 15
-4(2y) + 11y = 15
-8y + 11y = 15
3y = 15
Divide both sides by 3
3y/3 = 15/3
Y = 5
Again, substitute 5 for y in x= 2y
x = 2y
x = 2(5)
x = 10
Final answer : X = 10 and y = 5
Good luck!
Answer:
-1.60778117 I did it with a calculator
Answer: x = -0.3
Step-by-step explanation:
<u>Given expression</u>
1 - 3 (9x + 3) = 3x + 1
<u>Expand parentheses and apply the distributive property</u>
1 - 27x - 9 = 3x + 1
<u>Combine like terms</u>
(1 - 9) - 27x = 3x + 1
-8 - 27x = 3x + 1
<u>Subtract 3x on both sides</u>
-8 - 27x - 3x = 3x + 1 - 3x
-8 - 30x = 1
<u>Add 8 on both sides</u>
-8 - 30x + 8 = 1 + 8
-30x = 9
<u>Divide - 30 on both sides</u>
(-30)x / (-30) = 9 / (-30)
(-30)x / (-30) = 3 / (-10)

Hope this helps!! :)
