Answer 1

subtitude the value in the equation
first row,second column
when x=-6
y=-2x/3+7
y=-2(-6)/3+7
y=11

second row first column
when y=5
y=-2x/3+7
5=-2x/3+7
5-7=-2x/3
-2=-2x/3
x=3

third row second column
when x=15
y=-2x/3+7
y=-2(15)/3+7
y=-10+7
y=-3

last row first column
-12

Answer 2

the first one x is 6 and y is 11

the second one y is 5 and x is 3

the third one x is 15 and y is 17

the fourth one y is 15 and x is -12

Explanation:

to find the first answer you have to use the actual equation given and substitute the value of x in it

y=-2(-6)/3+7

=12/3+7

=4+7

=11

the second one is quite different because the value of y has been given and not x so you have to substitute the value of y in the equation which is 5

5=-2x/3+7

5-7=-2x/3

-2/1=-2x/3

-2x/-2=-6/-2

x=3

for the third one you have to solve it like the first one

y=-2(15)/3+7

=10+7

=17

the fourth one is similar to the second one

15=-2x/3+7

15-7=2x/3

8=2x/3

-2x/-2=24/-2

x=-12

I hope this helps
