Simplify the equation
-2x-3=4x-15

Add -2x to both sides to get 'x' on one side of the equation
-2x-3=4x-15
+2x   +2x

-3=6x-15

add 15 to both sides to isolate 6x
-3=6x-15
+15=6x+15

12=6x

divide both sides by 6 to get 'x' alone
12=6x
/6=/6

2=x

so your answer is 2=x or you can flip it and it will be the same, x=2

  B)  y = (x -7)(4x +3)

Step-by-step explanation:

For zeros p and q, factors of the function are (x -p) and (x -q).

For the given zeros, the factors are (x -7) and (x -(-3/4)). By multiplying the latter by 4, we can eliminate the fraction.

  y = (x -7)(4x +3)
