What is the best first step in solving the equation 4 + squrt(6x) = 5?

OLEGan [10]

The best answer to this question is to subtract 4 from both sides. This isolates the square root and sets you up for squaring both sides of the equation.

Step-by-step explanation:

Step 1: Define

Identify

8x + 3y = 20

x + 4y = 17

(1, 4)

Step 2: Check

Plug and verify the coordinates is a solution.

Substitute in point [1st Equation]: 8(1) + 3(4) = 20
Multiply: 8 + 12 = 20
Add: 20 = 20 $\checkmark$
Substitute in point [2nd Equation]: 1 + 4(4) = 17
Multiply: 1 + 16 = 17
Add: 17 = 17 $\checkmark$

∴ Since both equations work out, (1, 4) is a solution to the systems of equations.
