Question

4x - 3 = 2x + 7
what’s the value of x

Answer 1

Answer: X = 5

Step-by-step explanation: The target should be to reduce the equations to having either one term or polynomial on each side, starting with the right side. First, start with subtracting 2x from each side. Then, add three to both sides. Finally, divide both sides. You can also double-check the answer by substituting.

4x - 3 = 2x + 7

2x - 3 = 7 (Subtracted 2x)

2x = 10 (Added 3 to both sides)

10/2 (Divide both sides)

X = 5

4(5) - 3 = 2(5) + 7

17 = 17

Answer 2

x = 5

Explanation:

4x - 3 = 2x + 7

Add 3 to both sides.

4x = 2x + 10

Subract 2x from both sides.

2x = 10

Divide both by 2.

Final Answer: 5

If you wanted to check your answer, you can plug in 5 from the x's

4(5) - 3 = 2(5) + 7

17 = 17
