Solve the following equation for x.
3x - (2x - 3) = 2x + 9

x=-6

Step-by-step explanation:

3x-(2x-3)=2x+9

3x-2x+3=2x+9

x+3=2x+9

3=2x-x+9

3=x+9

x=3-9

x=-6

he earned 78.75 in interest.

step-by-step explanation:

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
