Question

Solve the following equation: x2-5=7

Answer 1

Answer:

x= 6

Step-by-step explanation:

Step 1: Write equation

2x - 5 = 7

Step 2: Solve for x

Add 5 to both sides: 2x = 12

Divide both sides by 2: x= 6

Step 3: Check

Plug in x to verify if it's a solution.

2(6) - 5 = 7

12 - 5 = 7

7 = 7
