Question

7-6x=-4x-6 -7x-7=4-8x

Answer 1

Ответ:

x=6  1/2 x=11

Пошаговое объяснение:

-6x+4x=-6-7

-2x= -13

x= -13 : (-2)

x= 6 1/2

-7x+8x=4+7

1x=11

x=11

Answer 2

Let's solve the two equations step by step:

1. 7 - 6x = -4x - 6

First, we want to isolate the variable 'x' on one side of the equation. To do that, we'll move all the terms containing 'x' to one side and the constant terms to the other side.

Add 4x to both sides: 7 - 6x + 4x = -4x + 4x - 6

Simplify: 7 - 2x = -6

Now, subtract 7 from both sides to isolate 'x': 7 - 2x - 7 = -6 - 7

Simplify: -2x = -13

Finally, divide by -2 to solve for 'x': x = -13 / -2 x = 6.5

So the solution for the first equation is x = 6.5.

2. -7x - 7 = 4 - 8x

Similarly, we want to isolate 'x' on one side of the equation.

Add 8x to both sides: -7x + 8x - 7 = 4 - 8x + 8x

Simplify: x - 7 = 4

Now, add 7 to both sides to isolate 'x': x - 7 + 7 = 4 + 7

Simplify: x = 11

The solution for the second equation is x = 11.

So, the solutions for the given system of equations are: x = 6.5 (from the first equation) and x = 11 (from the second equation).
