Question

(622+х) -439=40*79=х-(239+211)=3100:155=помогите решить пожалуйста

Answer 1

(622+х) -439=40*79
622+х=3160+439
622+х=3599
х=3599-622
х=2977

х-(239+211)=3100:155
х-450=20
х=20+450
х=470

Answer 2

To solve the equation (622 + x) - 439 = 40 * 79 = x - (239 + 211) = 3100 / 155, we can follow these steps:

Step 1: Simplify the equation - Start by simplifying the equation on both sides. - On the left side, we have (622 + x) - 439, which can be simplified to 183 + x. - On the right side, we have 40 * 79, which equals 3160. - So the equation becomes 183 + x = 3160.

Step 2: Solve for x - To solve for x, we need to isolate it on one side of the equation. - Subtract 183 from both sides of the equation: (183 + x) - 183 = 3160 - 183. - This simplifies to x = 2977.

Step 3: Verify the solution - To verify the solution, substitute the value of x back into the original equation and check if both sides are equal. - On the left side, we have (622 + x) - 439 = (622 + 2977) - 439 = 3599 - 439 = 3160. - On the right side, we have x - (239 + 211) = 2977 - 450 = 2527. - Since both sides of the equation are equal to 3160, we can conclude that x = 2977 is the correct solution.

Therefore, the solution to the equation (622 + x) - 439 = 40 * 79 = x - (239 + 211) = 3100 / 155 is x = 2977.
