Question

4×(у-9)=36 4у=36:9 4у=4

Answer 1

4y-36=36
4y=36+36
4y=72
y=18

Answer 2

Let's solve the equations step by step:

1. 4×(у-9) = 36 To solve this equation, we need to isolate the variable 'у' on one side of the equation. First, distribute the 4 on the left side:

4у - 4×9 = 36

Now, simplify further:

4у - 36 = 36

Next, add 36 to both sides of the equation to get '4у' alone:

4у = 36 + 36 4у = 72

So, the value of 'у' is 72/4, which is:

у = 18

Now let's check the second equation:

2. 4у = 36:9 Here, we are dividing both sides of the equation by 9 to solve for 'у'.

4у = 36 ÷ 9 4у = 4

You made a mistake in your calculation. 36 divided by 9 is 4, not 1. Therefore, the correct value for 'у' is:

у = 4

So, the correct value of 'у' is 4, not 18 as you mentioned in your calculations.
