Answer: (-5,1)
Step-by-step explanation:
x=-2y-3
4y-x=9
4y-(-2y-3)=9
4y+2y+3=9
6y+3=9
6y=6
y=1
x=-2y-3
x=-2-3
x=-5
Answer:
D 36
Step-by-step explanation:
<em>Write the information algebraically</em>
c = 3a
c + a = 48
c = children, a = adults
<em>In the second sentence (in bold), we can replace c with 3a</em>
c + a = 48 → 3a + a = 48
<em>Simplify</em>
3a + a = 48 → 4a = 48 → a = 12 (divide both sides by 4)
<em>We can then substitute or plug in a = 12 into the original equation:</em>
c + a = 48 → c + 12 = 48 → c = 36 (subtract 12 from both sides)
<h3>There are 36 children</h3>
I think its 9 because 5x+15=50 you subtract 15 from both sides and then divide.
There is no answer to this question, as you have not provided us with an equal sign.
If I assume that the equation truly is “h/3+ (-4) + -1 = 0” the answer would be h=15.
Comment down below if there are any specifications on t other parts of the equation.
