2x^-2 y^-2 if x = 3 y = -2

Question

Mathematics: 2x^-2 y^-2 if x = 3 y = -2

issacurlyheadka · Accepted Answer

y=4x−11

Step 1: Flip the equation.

4x−11=y

Step 2: Add 11 to both sides.

4x−11+11=y+11

4x=y+11

Step 3: Divide both sides by 4.

$\frac{4x}{4}$ = $\frac{y+11}{4}$

x= $\frac{1}{4} y$ + $\frac{11}{4}$

y=-8x + 13

Step 1: Flip the equation.

−8x+13=y

Step 2: Add -13 to both sides.

−8x+13+−13=y+−13

−8x=y−13

Step 3: Divide both sides by -8.

$\frac{-8x}{8}$ = $\frac{y- 13}{-8}$

x= $\frac{-1}{8}y$ + $\frac{13}{8}$
