Question

10×X=7490 90900:X=10 X×10=40070

Answer 1

   10×X=7490
x=7490/10
x=749

   90900:X=10
x=9090

X×10=40070
x=4007

Answer 2

10х=7490 90900:х= 10
х= 7490:10 х= 90900:10
х=749 х= 9090

х×10=40070
х= 40070:10
х = 4007

Answer 3

Let's solve these equations step by step.

1. 10×X=7490

To isolate X, we need to divide both sides by 10:

10×X/10 = 7490/10

X = 749

Therefore, X = 749 in the first equation.

2. 90900:X=10

To solve for X, we need to invert the fraction and multiply both sides by X:

X/90900 = 1/10

X = 90900/10

X = 9090

Therefore, X = 9090 in the second equation.

3. X×10=40070

To isolate X, we need to divide both sides by 10:

X×10/10 = 40070/10

X = 4007

Therefore, X = 4007 in the third equation.

So, we have solved for X in each of the three equations, and the values are:

• X = 749 in the first equation.
• X = 9090 in the second equation.
• X = 4007 in the third equation.
