Solve this equation for x in terms of y and z

7x - 5y - 2z = 4

What is he value of x when y = 5 and z = 3

x = 5

Step-by-step explanation:

Step 1: Set y to 5 and z to 3

7x - 5 (5) - 2 (3) = 4

7x - 25 - 6 = 4

7x - 31 = 4

Step 2: Add 31 to both sides

7x - 31 + 31 = 4 + 31

7x = 35

Step 3: Divide both sides by 7

7x / 7 = 35 / 7

x = 5

Answer: x = 5
