Question

3x-2y=3 2x+y=16
using cramers rule ​

Answer 1

Step-by-step explanation:

3x−2y=3;2x+y=16

Rewrite equations:

2x+y=16;3x−2y=3

Step: Solve2x+y=16for y:

2x+y=16

2x+y+−2x=16+−2x(Add -2x to both sides)

y=−2x+16

Step: Substitute−2x+16foryin3x−2y=3:

3x−2y=3

3x−2(−2x+16)=3

7x−32=3(Simplify both sides of the equation)

7x−32+32=3+32(Add 32 to both sides)

7x=35

7x

7

=

35

7

(Divide both sides by 7)

x=5

Step: Substitute5forxiny=−2x+16:

y=−2x+16

y=(−2)(5)+16

y=6(Simplify both sides of the equation)

Answer:

x=5 and y=6
