Question

Help! 1) 9*x-6*x=31-4*4 2) 11*x-9*x-13=59

Answer 1

1)
9*х-6*х=31-4*4
3х=31-16=15 |:3
Х=5

2)
11*х-9*х-13=59
2х=59+13=72 |:2
Х=36

Answer 2

Of course, I can help you solve these equations. Let's take them one by one.

1. 9x - 6x = 31 - 4*4

First, simplify both sides of the equation:

3*x = 31 - 16

Now, simplify the right side:

3*x = 15

Now, divide both sides by 3 to isolate x:

x = 15 / 3

x = 5

So, the solution to the first equation is x = 5.

2. 11x - 9x - 13 = 59

First, simplify both sides of the equation by combining like terms:

(11x - 9x) - 13 = 59

2*x - 13 = 59

Now, add 13 to both sides to isolate 2*x:

2*x = 59 + 13

2*x = 72

Finally, divide both sides by 2 to solve for x:

x = 72 / 2

x = 36

So, the solution to the second equation is x = 36.
