Question

18 - 8 = 19 - 6 78/(2*3) = 79 + (-9*6 - 3) 8*2 + (9 - 3) = 8 + ?

Answer 1

Если я правильно поняла, и все это одно уравнение то к 8 нужно прибавить 2, т.к. 18-8=10, а 10=8+2

Answer 2

18 - 8 = 19 - 6 78/(2*3) = 79 + (-9*6 - 3) 8*2 + (9 - 3) = 8 + 2

Answer 3

Let's solve each of these equations step by step:

1. 18 - 8 = 19 - 6 10 = 13 (This is not a true statement, so the equation is not valid.)

2. 78 / (2 * 3) = 79 + (-9 * 6 - 3) 78 / 6 = 79 + (-54 - 3) 13 = 79 + (-57) 13 = 22 (This is not a true statement, so the equation is not valid.)

3. 8 * 2 + (9 - 3) = 8 + ? 16 + 6 = 8 + ? 22 = 8 + ?

So, the third equation is valid, and the answer is: 8 + ? = 22

To find the value of "?", you can subtract 8 from both sides of the equation: ? = 22 - 8 ? = 14

So, the value of "?" is 14.
