Question

2(2 + х) + ( 4х - 1) · 3 = 10х - 7

Answer 1

4+2х+12х-3=10х-7

1+14х=10х-7

14х-10х= -7-1

4х= -8

х= -8÷4

х= -2

Answer 2

To solve the equation 2(2 + x) + (4x - 1) * 3 = 10x - 7 for the variable x, follow these steps:

Step 1: Distribute the terms on the left side of the equation:

2 * 2 + 2 * x + 3 * 4x - 3 * 1 = 10x - 7

Simplify the terms:

4 + 2x + 12x - 3 = 10x - 7

Step 2: Combine like terms on the left side of the equation:

14x + 1 = 10x - 7

Step 3: Subtract 10x from both sides of the equation to isolate the x terms on one side:

14x - 10x + 1 = -7

Simplify:

4x + 1 = -7

Step 4: Subtract 1 from both sides of the equation:

4x + 1 - 1 = -7 - 1

Simplify:

4x = -8

Step 5: Divide both sides by 4 to solve for x:

4x / 4 = -8 / 4

Simplify:

x = -2

So, the solution to the equation is x = -2.
