Question

(x+24)×30=900 x+24×30=900 x×20-240=360

Answer 1

(х+24)×30=900

30х+720=900

30х=900-720

30х=180

х=6

-------------------

х+24×30=900

х+720=900

х=900-720

х=180

---------------------

х×20-240=360

20х-240=360

20х360+240

20х=600

х=30

Answer 2

To solve the equations, let's work on them one by one:

1. (x + 24) × 30 = 900

To solve for x, we need to isolate it on one side of the equation. First, let's simplify the left side:

(x + 24) × 30 = 900 30x + 720 = 900 (Distributed the multiplication)

Now, let's isolate x by moving the constant term to the other side of the equation:

30x = 900 - 720 30x = 180

Finally, divide both sides by 30 to find the value of x:

x = 180 / 30 x = 6

2. x + 24 × 30 = 900

It seems this equation is the same as the first one, so we already have the value of x as 6.

3. x × 20 - 240 = 360

Let's solve this equation for x:

x × 20 - 240 = 360

Add 240 to both sides to move the constant term to the right side of the equation:

x × 20 = 360 + 240 x × 20 = 600

Now, divide both sides by 20 to find the value of x:

x = 600 / 20 x = 30

So, the solutions to the equations are: x = 6 (from equations 1 and 2) x = 30 (from equation 3)
