4. Solve using elimination.
4x -3y = 9
3x +2y = 11

x=3, y=1

Step-by-step explanation:

2(4x-3y=9) Multiply these two equations to cancel out the y using elimination

3(3x+2y=11)

8x-6y=18 Add these two equations to cancel out the y using elimination

9x+6y=33

17x=51 Solve for x

x=3

4(3)-3y=9 Plug in x=3 into the original equation

3y=3 Solve for y

y=1

use the power rule  

( a b ) n = a n b n

to distribute the exponent.

apply the product rule to  

3 x 2 y 3 . ( 3 x 2 ) 2 ( y 3 ) 2

apply the product rule to  

3 x 2 . 3 2 ( x 2 ) 2 ( y 3 ) 2

raise  

3

to the power of  

2 . 9 ( x 2 ) 2 ( y 3 ) 2 multiply the exponents in   ( x 2 ) 2

.

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 2 ⋅ 2 ( y 3 ) 2

multiply  

2   by   2 . 9 x 4 ( y 3 ) 2

multiply the exponents in  

( y 3 ) 2 .

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 4 y 3

⋅

2

multiply  

3   by   2 . 9 x 4 y 6
