4x-3+x=7x-3 solve x and show work easy to undertand please. Really appreciate it ^^
nalin [4]

Answer: x = 0

Step-by-step explanation:

4x − 3 + x = 7x − 3

Step 1: Simplify both sides of the equation.

4x − 3 + x = 7x − 3

4x + −3 + x = 7x + −3

(4x + x) + (−3) = 7x − 3(Combine Like Terms)

5x + −3 = 7x − 3

5x − 3 = 7x − 3

Step 2: Subtract 7x from both sides.

5x − 3 − 7x = 7x − 3 − 7x

−2x − 3 = −3

Step 3: Add 3 to both sides.

−2x − 3 + 3 = −3 + 3

−2x = 0

Step 4: Divide both sides by -2.

-2x/-2 = 0/-2

x = 0
