You have to insert 67 for y and then only solve the equation for X
67=-24x+379
x=? 

If you need more help let me know :)

y = amount left so y = 67

rewrite the equation as:

67 = -24x+379

subtract 379 from both sides

-312 = -24x

 divide both sides by -24

x = -312 / -24

x = 13

the answer is 13 weeks

kotegsom [21]

Answer:

(x,y)=(-1,-4)

Step-by-step explanation:

-4x + y = 0

+4x         +4x

y=4x

-5x - 2y = 13

+5x          +5x

-2y = 5x+13

-2(4x) = 5x+13

-8x=5x+13

-5x -5x

-13x/-13=13/-13

x=-1

Thus:

y=4x

y=4(-1)

y=-4

Winnie has 1/2 cup of flour in a mixing bowl.she adds more flour. winnie claims that she now has 3/7 cup of flour in the mixing
malfutka [58]

First, let's make 1/2 and 3/7 have the same denominator to make it easier to see. We know that there Least Common Multiple (LCM) is 14.

1/2=7/14

3/7=6/14

Wait a second... 3/7 is less than 1/2. This means that Winnie's statement is false because it is impossible that after adding more flour, she actually has less flour than what she started with.

Hope this helps! :)
