Question

(Х-93)*408=2856 4+(а-14:2)=30

Answer 1

408х-37944=2856
408х=2856+37944
408х=40800
х=100

4+а-14/2=30
4+а-7=30
а=30-4+7
а=33

Answer 2

(Х-93)*408=2856
408х-37944=2856
408х=2856+37944
408х=40800
Х=40800:408
Х=100
——————
4+(а-14:2)=30
4+а-7=30
а-3=30
а=30+3
а=33

Answer 3

To solve the given equations:

1. (Х-93) * 408 = 2856

First, let's solve for X:

Divide both sides by 408: (Х - 93) = 2856 / 408 Х - 93 = 7

Now, isolate X by adding 93 to both sides: Х = 7 + 93 Х = 100

So, the solution for the first equation is X = 100.

2. 4 + (а - 14) / 2 = 30

Let's solve for а:

Subtract 4 from both sides: (а - 14) / 2 = 30 - 4 (а - 14) / 2 = 26

Now, multiply both sides by 2 to isolate (а - 14): а - 14 = 2 * 26 а - 14 = 52

Add 14 to both sides: а = 52 + 14 а = 66

So, the solution for the second equation is а = 66.

To summarize:

1. Х = 100
2. а = 66
