Question

2(7x-2)+14x=4(2x+5)-8

Answer 1

2(7x-2)+14x=4(2x+5)-8

14x-4+14x=8x+20-8

28x-4=8x+12

28x-8x=12+4

20x=16

x=16/20

x=4/5

x=0,8

Answer 3

To solve the equation 2(7x - 2) + 14x = 4(2x + 5) - 8, follow these steps:

Step 1: Distribute the numbers on both sides of the equation.

On the left side: 2 * 7x = 14x 2 * (-2) = -4

So the left side becomes: 14x - 4 + 14x

On the right side: 4 * 2x = 8x 4 * 5 = 20 -8

So the right side becomes: 8x + 20 - 8

Step 2: Simplify both sides of the equation.

The equation now becomes: 14x - 4 + 14x = 8x + 20 - 8

Step 3: Combine like terms on both sides.

On the left side, combine the x terms: 14x + 14x = 28x

On the right side, combine the constant terms: 20 - 8 = 12

The equation becomes: 28x - 4 = 12

Step 4: Isolate x on one side of the equation.

Add 4 to both sides to move the constant term to the right side: 28x = 12 + 4 28x = 16

Step 5: Solve for x.

Divide both sides by 28 to get the value of x: x = 16 / 28 x = 4 / 7

So, the solution to the equation is x = 4/7.
