Answer:
x=10/3 y=17/3
Step-by-step explanation:
Use substitution to solve your equation. Plug in y=2x-1 into y=1/2x+4. This makes (2x-1)=1/2x+4. Simplify this to get 3/2x-1=4. Simplify it again to get 3/2x=5. No one likes fractions so multiply both sides by 2 to get 3x=10. Simplify this and get x=10/3. Plus 10/3 into one of the equations. You can pick anyone but I picked y=2x-1. Because you know x=10/3, you put y=2(10/3)-1. Simplify this and get y=20/3-1. Convert 1 into a fraction and get y=20/3-3/3. Simplify this and get y=17/3.
Therefore,
x=10/3 y=17/3

Step-by-step explanation:
Answer:
$65/hour
Step-by-step explanation:
Let C(h) represent the total amount payable to the plumber. Then:
C(h) = $75 + (rate)(2 hr) = $205. Solve for the "fixed hourly rate."
Subtracting $75 from both sides, we get:
(rate)(2 hr) = $130.
Dividing both sides by (2 hr) results in (rate) = $65/hour
