Given that y=3(4x - 3)+5, find the value of x when y=-2.

x=-2

Step-by-step explanation:

Distribute the 3 with the parenthesis to make the new equation -2=12x-9+5.

Combine like terms. -2=12x-4.

Move -4 to other side. -6=12x.

Divide by -6. x=-2

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

3 3 6, because in every triangle the longer side is always shorter than the sum of the other two
