Given the function g(x)=3x-7, determine when g(x)=-4

sp2606 [1]

You have the following function:

g(x) = 3x - 7

In order to determine th value of x when g(x) = -4, you equal the previous expression to -4 and solve for x, just as follow:

g(x) = 3x - 7 replace g(x) = -4

-4 = 3x - 7 add 7 both sides

-4 + 7 = 3x simplify

3 = 3x divide by 3 both sides

3/3 = x

x = 1

Hence, the anser is x = 1

Answer:

$x = -\frac{12}{5}$

Step-by-step explanation:

To solve the equation, isolate x. Whatever you do to isolate x one on side, you must do to the other.

1) Multiply both sides by 9 to get rid of the fractions.

$\frac{21-4x}{9} +\frac{8x+15}{3} = 2 \\21-4x + 3(8x + 15) =18 \\$

2) Distribute the 3 to 8x and 15. Then, combine like terms.

$21-4x + 24x + 45 = 18 \\66 + 20x = 18$

3) Move the 66 to the other side, subtracting 18 by 66, then divide each side by 20 to finally isolate x.

$20x = -48\\x = -\frac{48}{20} \\x =- \frac{12}{5}$

Thus, $x = -\frac{12}{5}$ .
