Question

solve for X and Y 6 x minus 2 Y is equals to minus 9 3 ;x minus y = 2 - 12​

Answer 1

Answer:

Step-by-step explanation:

6x-2y= -93------------------------------1

x-y=2-12---------------------------------2

first do with 2

x-y= -10

x=y-10-------------------------------------3

now substitude 3 in 1

6(y-10)-2y= -93

6y-60-2y=-93

4y-60=-93

4y=60-93

y=-33÷4=-8.25

3

x-y=-10

x+8.25=-10

x=-18.25

check

6x-2y=-93

-109.5+16.5=-93

Answer 2

6x-2y=-93

2(3x-y)=-93

3x-y=-93/2

3x-y=-46.5

x-y=2-12

x-y=-10

x=-10+y

x=y-10

3(y-10)-y=-46.5

3y-30-y=-46.5

2y-30=-46.5

2y=-46.5+30

2y=-16.5

y=-16.5/2

Y=-8.25

x=-8.25-10

X=-18.25
