Solve for x and y<br><br> 2x+7=3y-1

zlopas [31]

To solve for x and y, isolate each variable and simplify your equation:

Solve for x:
2x+7=3y-1 (Subtract 7 on each side)
2x=3y-8 (Divide by 2 on each side)
x= $\frac{3y}{2} -4$

Solve for y:
2x+7=3y-1
2x+8=3y (Add 1 on each side)
$\frac{2x}{3} + \frac{8}{3}$ =y (Divide by 3)
y= $\frac{2x}{3} + \frac{8}{3}$

shutvik [7]

First make the denominators the same = 4 5/20 - 3 12/20. Then make them improper fractions= 85/20-72/20= 13/20. Since that is already simplified the answer is 13/20.

Debbie cut a cord into sixths . She used five of the to make necklaces . She used equal lengths of the remaining cord for each o

Brut [27]

So she used $\frac{5}{6}$ of the cord to make necklaces.
$1- \frac{5}{6} = \frac{1}{6}$

She splits the $\frac{1}{6}$ length into 4 equal lengths.
To divide a fraction by a fraction, you multiply it by its reciprocal.
$\frac{1}{6} ( \frac{1}{4})$
$=\frac{1}{24}$

She used $\frac{1}{24}$ of the original chord to make each bracelet.
