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
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
