Question

3*х=82+11 ; 78:х=14+12​

Answer 1

3 * х = 82 + 11

3x = 93

x = 31

78 : х = 14 + 12​

78 : x = 26

x = 78 : 26

x = 3

Answer 2

Let's solve the two equations step by step:

1. 3x = 82 + 11

First, add 82 and 11:

3x = 93

Now, to isolate x, divide both sides of the equation by 3:

3x / 3 = 93 / 3

x = 31

So, the solution to the first equation is x = 31.

2. 78 / x = 14 + 12

First, add 14 and 12:

78 / x = 26

Now, to isolate x, you can multiply both sides of the equation by x to get rid of the fraction:

(78 / x) * x = 26 * x

78 = 26x

Now, divide both sides by 26 to solve for x:

78 / 26 = 26x / 26

3 = x

So, the solution to the second equation is x = 3.

Therefore, the solutions to the two equations are:

1. x = 31
2. x = 3
