Answer:
X=4
Step-by-step explanation:
-2x+1=-4x+9 Firstly subtract 1 from each side
-2x+1-1+-4x+9-1 Simplify by subtracting
-2x=4x+8 Add 4x to both sides
-2+4x=-4+8+4x Simplify by combining like terms
2x=8 Divide both sides by the same term
2x/2=8/2 Divide the numbers
x=4
Final answer: X=4
Enjoy! ^^
