Question

30*х=40-20 у-9=76-60​

Answer 1

30х=40-20
30х=20
Х=20/30
Х=2/3

У-9=76-60
У-9=16
У=25

Answer 2

Відповідь:

х = 2/3

у = 25

Покрокове пояснення:

30×х = 40 - 20 = 20

х = 20 / 30 = 2/3

у - 9 = 76 - 60 = 16

у = 16 + 9 = 25

Answer 3

To solve the equations:

1. 30x = 40 - 20
2. y - 9 = 76 - 60

Let's start with the first equation:

1. 30x = 40 - 20

First, simplify the right side of the equation:

30x = 20

Now, to isolate x, divide both sides by 30:

x = 20/30

x = 2/3

So, the solution to the first equation is x = 2/3.

Moving on to the second equation:

2. y - 9 = 76 - 60

First, simplify the right side of the equation:

y - 9 = 16

Now, to isolate y, add 9 to both sides:

y = 16 + 9

y = 25

So, the solution to the second equation is y = 25.

The solutions to the two equations are:

1. x = 2/3
2. y = 25
