Question

5×-6=3×+6 если 1)0, 2)0,2 ,3)6,4)-6

Answer 1

$5 x - 6 = 3x + 6 \\ 5x - 3x = 6 + 6 \\ 2x = 12 \\ x = 12 \div 2 \\ x = 6$

Answer 2

To solve the equation 5×-6=3×+6 for each given value, you simply substitute the value of x and see if the equation holds true. Let's go through each case:

1. If x = 0: 5× - 6 = 3× + 6 5(0) - 6 = 3(0) + 6 0 - 6 = 0 + 6 -6 = 6

The equation is not true when x is 0.

2. If x = 0.2: 5× - 6 = 3× + 6 5(0.2) - 6 = 3(0.2) + 6 1 - 6 = 0.6 + 6 -5 = 6.6

The equation is not true when x is 0.2.

3. If x = 6: 5× - 6 = 3× + 6 5(6) - 6 = 3(6) + 6 30 - 6 = 18 + 6 24 = 24

The equation is true when x is 6.

4. If x = -6: 5× - 6 = 3× + 6 5(-6) - 6 = 3(-6) + 6 -30 - 6 = -18 + 6 -36 = -12

The equation is not true when x is -6.

So, out of the given values:

1. x = 0 does not satisfy the equation.
2. x = 0.2 does not satisfy the equation.
3. x = 6 satisfies the equation.
4. x = -6 does not satisfy the equation.
