Answer 2

To solve this equation, we need to apply the order of operations (PEMDAS) and perform the calculations in the correct order. PEMDAS stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

First, let's simplify the expressions inside the parentheses:

5760 ÷ 90 = 64

Next, let's simplify the expressions on the left side of the equation:

86 • 35 = 3010 2000 ÷ 8 = 250

So, the left side of the equation becomes:

3010 + 250 = 3260

Now, let's simplify the expressions on the right side of the equation:

38430 ÷ 7 = 5490

So, the right side of the equation becomes:

64 • 52 + 5490 = 8868

Finally, let's substitute the simplified expressions back into the original equation:

3260 - 8868 = -5608

Therefore, the solution to the equation 7740 : 86•35+2000:8-(5760:90)•52+38430:7= is -5608.
