Question

6х-21=88-4х=-63х-15=х+3​

Answer 1

Пошаговое объяснение:

$1) 6x-21=8\\6x = 8+21\\6x=29\\x=\frac{29}{6}\\\\2)8-4x=-6\\-4x = -6-8\\-4x=-14\\-x=\frac{-14}{4} \\-x = 3.5\\\\3) 3x-15=x+3\\3x-x=3+15\\2x=18\\x=\frac{18}{2}\\x=9$

Answer 2

It appears that you have a system of three linear equations with one variable, which is represented by 'x.' Let's solve this system step by step:

1. 6x - 21 = 88

First, add 21 to both sides of the equation to isolate the variable term:

6x - 21 + 21 = 88 + 21

This simplifies to:

6x = 109

Now, divide both sides by 6 to solve for 'x':

6x / 6 = 109 / 6

x = 109 / 6

2. -4x = -63

To solve for 'x' in this equation, divide both sides by -4:

(-4x) / (-4) = (-63) / (-4)

x = 63 / 4

3. -15 = x + 3

To solve for 'x' in this equation, subtract 3 from both sides:

-15 - 3 = x + 3 - 3

-18 = x

So, you have three different values for 'x' from the three equations:

x = 109 / 6 x = 63 / 4 x = -18

These are the solutions to the system of equations.
