Answer:
-10
Step-by-step explanation:
combine like terms -5x+9=59 subtract 9 from both side and get -5x=50 so x=-10
<span>x=number of brown shoes
2x=number of black shoes (twice as many black shoes as brown shoes)
so x+2x=66
add like terms 3x=66
solve for x by dividing 3; x=22
so there are 22 brown shoes and 44 black shoes (2 x 22= 44)</span>
Because there are two variables in this equation, you cannot solve for answers. However, I'll assume that you want to get this into slope intercept form as that is the most common way to graph these. The answer in that case is y = 2x - 2
<span>1/2 (y-3)= 1/2 + (x-3) ---> Start by multiplying both sides by 2
(y - 3) = 1 + 2x - 6 ---> now add 3 to each side
y = 3 + 1 + 2x - 6 ----> now simplify like terms.
y = 2x - 2 </span>
125x = 25
x = 0,2
There you go :)
