Question

Hello anyone that can help me with these please

Answer 1

13 (x= -2, y= 1)

14 (x=3, y= -4)

Explanation:

1 x+5y=3

3x-2y=-8

u gonna add 3 into x and make it negative

2 -3x-15y=-9

3x-2y=-8

x will be gone since 3x-3x

3 -17y=-17

y= 1

going to add y into x+5y=3

x+5=3

x=-2

question 14

y=2x-10

y=-4x+8

add - to everything in the bottom

y=2x-10

-y=4x-8

0=6x-18

18=6x

3=x

add 3 into x in y=2x-10

y=6-10

y=-4
