Answer:
4 = 3x
Step-by-step explanation:
9-5=9x-6x
Combine like terms
4 = 3x
We can solve for x
Divide by 3
4/3 = 3x/3
4/3 =x
If I got it right it is 9.59166305.
Substitute y = 3x + 15 to the equation -4x + 7y = 20:
-4x + 7(3x + 15) = 20 <em>use distributive property</em>
-4x + (7)(3x) + (7)(15) = 20
-4x + 21x + 105 = 20 <em>subtract 105 from both sides</em>
17x = -85 <em>divide both sides by 17</em>
x = -5
Substitute the value of x to the equation y = 3x + 15:
y = 3(-5) + 15
y = -15 + 15
y = 0
<h3>Answer: x = -5 and y = 0</h3>
I think it would be 27.38ᴹ2
