Question

B) 2y + 7y + 78 = 1581;​

Answer 1

Ответ:

2y + 7y +78 = 1581

9y +78 = 1581

9y = 1581 - 78

9y = 1503

y = 167

Пошаговое объяснение:

Answer 2

Ответ:

9y=1503

y=1503/9

y=167

Answer 3

To solve the equation 2y + 7y + 78 = 1581, you need to combine like terms and then isolate the variable y on one side of the equation. Here's the step-by-step process:

1. Combine like terms on the left-hand side of the equation: 2y + 7y = 9y

2. Rewrite the equation with the combined terms: 9y + 78 = 1581

3. Now, isolate the variable y by moving the constant term (78) to the other side of the equation: 9y = 1581 - 78 9y = 1503

4. Finally, solve for y by dividing both sides by the coefficient of y (which is 9): y = 1503 / 9 y = 167

So, the solution to the equation is y = 167.
