Math Problem Statement

X=2 x×5+10×5÷2

Solution

Let's break it down step by step.

Given:
x=2x = 2
and the expression:
x×5+10×5÷2x \times 5 + 10 \times 5 \div 2

Now, substitute x=2x = 2 into the expression:

2×5+10×5÷22 \times 5 + 10 \times 5 \div 2

First, solve the multiplication and division (following the order of operations: multiplication and division first, from left to right):

2×5=102 \times 5 = 10

Next:

10×5=50and then50÷2=2510 \times 5 = 50 \quad \text{and then} \quad 50 \div 2 = 25

Now, add the results:

10+25=3510 + 25 = 35

So, the final result is:

3535
