Question

89 × (б + 13) = 7120

Answer 1

89*(b+13)=7120;
b+13=7120:89;
b+13=80;
b=80-13;
b=67

Answer 2

89×(б+13)=7120
б+13=7120/89
б+13=80
б=67

Answer 3

To solve the equation, we need to find the value of the variable "б." Let's proceed step-by-step:

1. First, we'll simplify the equation: 89 × (б + 13) = 7120

2. Next, we'll remove the parentheses by applying the distributive property: 89б + 89 × 13 = 7120

3. Now, let's perform the multiplication on the left side of the equation: 89б + 1157 = 7120

4. To isolate the variable "б" on one side, we need to get rid of the constant term (1157) by subtracting it from both sides of the equation: 89б = 7120 - 1157

5. Calculate the result on the right side: 89б = 5963

6. Finally, to find the value of "б," divide both sides by 89: б = 5963 / 89

Now, let's calculate the value of "б": б ≈ 67

So, the value of the variable "б" is approximately 67, and you can verify this by substituting "б = 67" back into the original equation and checking if both sides are equal.
