Question

What is the value of x in the eqaution 7x+3=4x-9

Answer 1

-4

Explanation:

Step 1: Subtract 4x from both sides.

7x+3−4x=4x−9−4x

3x+3=−9

Step 2: Subtract 3 from both sides.

3x+3−3=−9−3

3x=−12

Step 3: Divide both sides by 3.

3x /3 = −12 /3

x=−4

Answer 2

x = -4

Explanation:

7x + 3 = 4x - 9

7x - 4x + 3 = 4x - 4x - 9

3x + 3 = -9

3x + 3 - 3 = -9 - 3

3x = -12

x = -4
