Given the equation - 2x + 7y = -25 find the value of y if the ordered pair (2,y) is a solution.
A 19.5
B -3
C -19.5
D 3

y=-3

Step-by-step explanation:

-2x+7y=-25

put x=2 in the above equation

-2(2)+7y=-25

-4+7y=-25

adding 4 on both sides

-4+4+7y=-25+4

7y=-21

dividing 7 on both sides

7y/7=-21/7

y=-3

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.

−3x
