Sole the equation. check your solution 2.5 y + 6=4.5y-1

3.5 = y

Step-by-step explanation:

2.5y + 6 = 4.5y - 1

2.5y + 7 = 4.5y

7 = 2y

3.5 = y

Check:

2.5y + 6 = 4.5y - 1

2.5(3.5) + 6 = 4.5(3.5) - 1

2.5(3.5) + 7 = 4.5(3.5)

8.75 + 7 = 15.75

15.75 = 15.75

Step-by-step explanation:

Start by subtracting from both sides of the equation:

Subtract from both sides of the equation:

Divide both sides of the equation by the coefficient of , which is :

_

Check your solution by substituting the solved value of () into the initial equation:

Since both sides of the equation are equal to each other, our solution is correct!
