x=37

Answer 3

Let's solve the given equations step by step:

Equation 1: X + 39 = 786 × 4

To solve this equation, we need to isolate X on one side. We'll start by subtracting 39 from both sides:

X + 39 - 39 = 786 × 4 - 39

This simplifies to:

X = 3144 - 39

X = 3105

Therefore, the value of X in the first equation is 3105.

Equation 2: 4X - 12 = 75/3

To solve this equation, we'll simplify the right side first. 75 divided by 3 equals 25, so the equation becomes:

4X - 12 = 25

Next, we'll isolate 4X by adding 12 to both sides:

4X - 12 + 12 = 25 + 12

This simplifies to:

4X = 37

Finally, we'll solve for X by dividing both sides by 4:

4X/4 = 37/4

X = 37/4

So, the value of X in the second equation is 37/4 or 9.25.

To summarize:

• In the first equation, X = 3105.
• In the second equation, X = 9.25 or 37/4.
