5(2*5+7)-0(8-21*5)=4(5*5+3)-6*5+3

Let's solve the equation step by step.

Starting with the left side:

1. Calculate inside the parentheses:

   • \(2 \times 5 + 7 = 10 + 7 = 17\)
   • \(8 - 21 \times 5 = 8 - 105 = -97\)

2. Now, substitute back into the expression:

   • Left side: \(5(17) - 0(-97)\)

3. Simplify:

   • \(5 \times 17 = 85\)
   • \(0 \times -97 = 0\)
   • So, left side = \(85 - 0 = 85\)

Now let's evaluate the right side:

1. Calculate inside the parentheses:

   • \(5 \times 5 + 3 = 25 + 3 = 28\)

2. Now substitute back into the expression:

   • Right side: \(4(28) - 6 \times 5 + 3\)

3. Simplify:

   • \(4 \times 28 = 112\)
   • \(6 \times 5 = 30\)
   • So, right side = \(112 - 30 + 3\)

4. Combine:

   • \(112 - 30 = 82\)
   • \(82 + 3 = 85\)

Now we can compare both sides:

• Left side = 85
• Right side = 85

Since both sides are equal, the equation is correct:

Final Answer: True (85 = 85)
