Question

(223 -m)+(145-n) = 108

Answer 1

1)223+145=368

2)368-108=260

3)260:2=130

m=130

n=130

Вот и всё!

Answer 2

Let's solve the equation step by step:

(223 - m) + (145 - n) = 108

First, simplify the parentheses:

368 - (m + n) = 108

Next, isolate the variable (m + n) by subtracting 368 from both sides:

• (m + n) = 108 - 368
• (m + n) = -260

To remove the negative sign, multiply both sides by -1:

m + n = 260

Therefore, the solution to the equation is m + n = 260.
