Hello there,

So we are solving this equation for x and the equation is as follows:

  • 3(x + 6) = -9

First we are going to distribute the 3 inside the parentheses:

  • 3x + 18= = -9

Now we subtract 18 from both sides:

  • 3x = -27

Lastly we are going to divide both sides by 3:

  • x = -9

So the answer to given equation would have to be x = -9.

Hope I helped,

Amna

Let's have Steve's age be <em>x</em><em />, and his father's age be <em>f</em>
Then, we can set up equations
Steve is one-fourth as old as his father goes to an equation as x=(1/4)f
In five years (x+5), Steve will be one-third as old as his father will be (f+5). This goes to an equation as x+5=(1/3)(f+5)
We can then solve the first equation for either variable (I will be doing f), and plug it in for a system of equations. 

x=(1/4)f
4x=f ← plug that in for f in the next equation

x+5 = (1/3)(4x+5) ← Solve this for x
3(x+5)=4x+5
3x+15=4x+5
3x+10=4x
10=1x
x=10

Therefore, Steve's age is 10. His father's age is <em>f=4x, </em>plug in 10 for x, and his father's age is 40
