Answer 2

To solve the given equations, we need to find the values of variables x and y. Let's solve each equation step by step:

1. 122.4 ÷ x = 12

To find the value of x, we'll first isolate x on one side of the equation by dividing both sides by 12.

122.4 ÷ 12 = x

x = 10.2

So, the value of x is 10.2.

2. 76.56 - x = 8.794

To find the value of x, we need to isolate x on one side of the equation. We'll do that by subtracting 8.794 from both sides:

76.56 - 8.794 = x

x = 67.766

So, the value of x is 67.766.

3. 5.3y + 3.7y + 4.6 = 46.9

Combine the like terms on the left side of the equation:

(5.3y + 3.7y) + 4.6 = 46.9

9y + 4.6 = 46.9

Next, isolate y by subtracting 4.6 from both sides of the equation:

9y = 46.9 - 4.6

9y = 42.3

Finally, divide both sides by 9 to find the value of y:

y = 42.3 ÷ 9

y = 4.7

So, the value of y is 4.7.

To summarize:

1. x = 10.2
2. x = 67.766
3. y = 4.7
