Question

1.x+3y=8 x=? 2.5y-x=7 x=? 3.3x+2y=5 x=?

Answer 1

Ответ:

8-3y  -7+5y  (5-2y)/3

Объяснение:

1) x=8-3y  2) -x=7-5y x=-7+5y  3) 3x=5-2y x= (5-2y)/3

Answer 2

To find the values of x in each equation, we need to solve the systems of linear equations. Let's solve them one by one:

1. x + 3y = 8

To find x, we can isolate it by subtracting 3y from both sides of the equation:

x = 8 - 3y

2. 5y - x = 7

To find x, we can isolate it by subtracting 5y from both sides of the equation:

x = 5y - 7

3. 3.3x + 2y = 5

To find x, we can isolate it by subtracting 2y from both sides of the equation and then dividing by 3.3:

x = (5 - 2y) / 3.3

So, the values of x in each equation are:

1. x = 8 - 3y
2. x = 5y - 7
3. x = (5 - 2y) / 3.3

Please note that in the third equation, x is expressed in terms of y. If you have values for y, you can substitute them in the respective equations to find the corresponding x values.
