Answer 2

Let's solve the given equations step by step.

Equation 1: X • 7 + 4678 • 3 = 46780

To solve this equation, we'll apply the order of operations (PEMDAS/BODMAS) and simplify:

X • 7 + 4678 • 3 = 46780

Multiply the numbers:

7X + 14034 = 46780

Subtract 14034 from both sides:

7X = 32746

Divide both sides by 7:

X = 32746 / 7

X ≈ 4678

Therefore, the value of X is approximately 4678.

Equation 2: 3576 · 7 = 7152 + a · 5

To solve this equation, we'll again apply the order of operations (PEMDAS/BODMAS) and simplify:

3576 · 7 = 7152 + a · 5

Multiply the numbers:

25032 = 7152 + 5a

Subtract 7152 from both sides:

25032 - 7152 = 5a

17880 = 5a

Divide both sides by 5:

a = 17880 / 5

a = 3576

Therefore, the value of a is 3576.

To summarize the solutions:

• X ≈ 4678
• a = 3576
