Answer:

x=-2

Step-by-step explanation:

25+6x=21+4x

Step 1: Simplify both sides of the equation.

6x+25=4x+21

Step 2: Subtract 4x from both sides.

6x+25−4x=4x+21−4x

2x+25=21

Step 3: Subtract 25 from both sides.

2x+25−25=21−25

2x=−4

Step 4: Divide both sides by 2.

x=−2

First subtract 21 from each side then you get 4+6x=4x then you subtract 6x from each side and get 4=-2x lastly you divide -2 from both sides your answer will be -2=x
