А )6877-х =2000+984 б ) а +354=413+48 в )29400÷х =700×21 г )419+х =209×4

Answer 1

А) 6877-х=2000+984
6877-х=2984
-х=2984-6877
х=-2984+6877
х=3893
б) а+354=413+48
а+354=461
а=461-354
а=107
в) 29400/х=700*21
29400/х=14700
х=29400/14700
х=2
г) 419+х=209*4
419+х=836
х=836-419
х=417

Answer 2

а) To solve the equation 6877x = 2000 + 984, you need to isolate x on one side of the equation.

First, simplify the right side of the equation:

2000 + 984 = 2984

Then, divide both sides by 6877:

x = 2984/6877

So the solution is x = 0.434.

б) To solve the equation a + 354 = 413 + 48, you need to isolate a on one side of the equation.

First, simplify the right side of the equation:

413 + 48 = 461

Then, subtract 354 from both sides:

a + 354 - 354 = 461 - 354

Simplifying further:

a = 107

So the solution is a = 107.

в) To solve the equation 29400/x = 700 * 21, you need to isolate x on one side of the equation.

First, simplify the right side of the equation:

700 * 21 = 14700

Then, multiply both sides by x:

29400 = 14700 * x

Finally, divide both sides by 14700:

x = 2

So the solution is x = 2.

г) To solve the equation 419 + x = 209 * 4, you need to isolate x on one side of the equation.

First, simplify the right side of the equation:

209 * 4 = 836

Then, subtract 419 from both sides:

x + 419 - 419 = 836 - 419

Simplifying further:

x = 417

So the solution is x = 417.
