Y+6x=5 (a) (0, )(b) (3, ) find the missing coordinate to complete the ordered pair solution to the given linear equation .

a) y+6x=5 if x= -1  then y+6(-1)=5 then y = 11

b) same thing if x = 3 then y+6(3)=5 y+18=5  subtract both sides by -18 and leave y on left then add 5+(-18)= 13 then y=13

B same as above

question (a) asks you to solve for y because x is -2

(b) asks you to solve for x because y is known

3x+2y=-6 if y = 3 you write 3x+2(3)=-6 3x+6=-6 move the +6 over to right side by subtracting 6 from both side 3x=-6 + -6 so 3x=-12 to get rid of the 3 and only leave the x you want to divide both side by 3 then x= -12/3 then the answer would be x=-4

How about this?

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
