You need to isolate the variables. For the first equation add x to both sides, which leaves you with y.
For the second equation, divide each side by 2 leaving you with
x= 6+y. Subtract y from each side. Subtract x from both sides. Now you have y= x + 6.
Now graph those equations.

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
f(x) = 4(2)ˣ
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em> [Function f(x)]: f(-3) = 4(2)⁻³
- Exponents: f(-3) = 4(1/8)
- Multiply: f(-3) = 1/2
