Question

4x+7+2x+5 solve for X​

Answer 1

Answer:

x = - 1

Step-by-step explanation:

Let's solve

4x + 7 = 2x + 5

Subtract 2x from both sides.

4x + 7 −2x = 2x + 5 −2x

2x + 7 = 5

Subtract 7 from both sides.

2x + 7 − 7 = 5 −7

2x = −2

Divide both sides by 2.

2x / 2 = −2 / 2

x = −1

Answer 2

Answer:

Simplifying

4x + -7 = -2x + -5

Reorder the terms:

-7 + 4x = -2x + -5

Reorder the terms:

-7 + 4x = -5 + -2x

Solving

-7 + 4x = -5 + -2x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '2x' to each side of the equation.

-7 + 4x + 2x = -5 + -2x + 2x

Combine like terms: 4x + 2x = 6x

-7 + 6x = -5 + -2x + 2x

Combine like terms: -2x + 2x = 0

-7 + 6x = -5 + 0

-7 + 6x = -5

Add '7' to each side of the equation.

-7 + 7 + 6x = -5 + 7

Combine like terms: -7 + 7 = 0

0 + 6x = -5 + 7

6x = -5 + 7

Combine like terms: -5 + 7 = 2

6x = 2

Divide each side by '6'.

x = 0.3333333333

Simplifying

x = 0.3333333333
