Answer:

y= 5 and -3

Step-by-step explanation:

subtract 7 from both sides to get y^2-2y-15=0

factor the equation to get (y-5)(y+3)=0

add five on both sides to get y=5 and subtract 3 on both sides to get y=-3

How many solutions does the following equation have?<br> -6(x + 7) = -4.x - 2

mestny [16]

Answer:

x=-20

Step-by-step explanation:

Given

-6(x+7)= -4x - 2

First of all, we have to solve brackets

So,

-6x-42=-4x-2

To find the solution of this equation, we have to isolate x on one side of the equation.

Adding 4x on both sides

-6x-42+4x = -2-4x+4x

-2x-42 = -2

Adding 42 on both sides

-2x-42+42 = -2+42

-2x=40

Dividing both sides by -2

-2x/2 = 40/-2

x = -20

The equation has only one solution which is x=-20 ..
