Question

5*(8+a)= (x+y)*15= 7*(x-9)= a*(x-y)= 12*(a+b)=

Answer 1

Ответ:5*(8+а)=40+5a

(x+y)*15=15x+15y

7*(x-9)=7x-63

a*(x-y)=ax-ay

12*(a+b)=12a+12b

Пошаговое объяснение:

Answer 2

40+5а
15x+15y
7x-63
ax-ay
12a+12b

Answer 3

To solve these equations, let's break them down one by one:

Equation 1: 5*(8+a) = (x+y)*15

Expanding the left side: 40 + 5a = 15(x+y)

Equation 2: 7*(x-9) = a*(x-y)

Expanding both sides: 7x - 63 = ax - ay

Equation 3: 12*(a+b) = ?
