Question

5x=-y+6 solve for y when x =1,2,3

Answer 1

When x = 1
5(1) = -y + 6
5 = -y + 6
y = 6 - 5 = 1

When x = 2
5(2) = -y + 6
10 = -y + 6
y = 6 - 10 = -4

When x = 3
5(3) = -y + 6
15 = -y + 6
y = 6 - 15 = -9

Answer 2

Test 1 in for x

5(1)= -y +6
5= -y+6
Subtract 6 from both sides

-1 = -y

Divide by -1 to get 1=y

x=2
5(2)= -y +6
10= -y+6

Subtract 6 from both sides
4= -y

Divide by -1

-4=y
---------------------------
X=3
5(3)= -y +6
15= -y +6

Subtract 6 from both sides
9= -y

Divide by -1
-9 = y
