I'm having problem understanding 6.3=0.9y can somebody help me. Do I add or multiply,
divide
6.3 = .9y
6.3/.9 = .9y/.9
7 = y
What is x+7.72=19
To solve the equation 6.3 = 0.9y, you need to isolate the variable y by performing algebraic operations.
To start, you want to isolate y on one side of the equation. Here's how we can do it step-by-step:
1. Since 0.9 is multiplied by y, you need to perform the inverse operation to remove the multiplication. In this case, you'll divide both sides of the equation by 0.9. This step cancels out the multiplication on the right side:
6.3 ÷ 0.9 = 0.9y ÷ 0.9
2. Simplify the left side of the equation:
7 = y
Therefore, the solution to the equation 6.3 = 0.9y is y = 7.
By dividing both sides of the equation by 0.9, you remove the multiplication and solve for y.
