20 + 17y = -6 + 15y Can you help me find y?

MariettaO [177]

20 + 17y = -6 + 15y

First, regroup your terms.
$20 + 17y = 15y - 6$
Second, take away '15y' from each side.
$20 + 17y - 15y = -6$
Third, subtract '17y - 15y' to get '2y'.
$20 + 2y = -6$
Fourth, take away '20' from both sides.
$2y = -6 - 20$
Fifth, simplify '-6 - 20' to get '-26'.
$2y = -26$
Sixth, divide both sides by '2'.
$y = -\frac{26}{2}$
Seventh, how many times goes 2 go into 26? 26 ÷ 2 = 13.
$y = -13$

Answer: y = -13

Answer

x=-2 and y=-3

Step-by-step explanation:

Step: Solvey=5x+7for y:

Step: Substitute5x+7 for y in 3x+y=−9:

3x+y=−9

3x+5x+7=−9

8x+7=−9(Simplify both sides of the equation)
