Find x in the equation: 2x + 9 = 5x - 12

x = 7

Step-by-step explanation:

Add 12 to both sides:

2x + 9 = 5x - 12

2x + 21 = 5x

Subtract 2x from both sides:

21 = 3x

Divide each side by 3:

7 = x

So, x = 7

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
