Question

Решить пример 90 × ( m - 8) + 60 = 150

Answer 1

90м-720+60=150 90м=150+720-60 90м=810 м=810÷90 м=9

Answer 2

To solve the equation, follow these steps:

1. First, isolate the term containing the variable (m) by performing inverse operations to move the constant terms to the other side of the equation.
2. Then, solve for the variable (m) by dividing both sides by the coefficient of the variable.

Let's solve it step by step:

Step 1: 90 × (m - 8) + 60 = 150

First, get rid of the constant term on the left side of the equation by subtracting 60 from both sides:

90 × (m - 8) = 150 - 60 90 × (m - 8) = 90

Step 2: Now, isolate the variable term (m - 8) by dividing both sides by 90:

(m - 8) = 90 / 90 (m - 8) = 1

Step 3: Finally, solve for the variable (m) by adding 8 to both sides:

m = 1 + 8 m = 9

So the solution to the equation is m = 9.
