#x=3#

Explanation:

1. Use the distributive property and combine like terms
#4+4x=6x-2#

2. Subtract 4x from both sides
#4=2x-2#

3. Solve for x
#4=2(3)-2#
#4=6-2#
#4=4#
#x=3#

Now that we know what x is, we can substitute for x in the original equation to check our answer
#4-7(3)+11(3)=-2(-3(3)+1)#
#4-21+33=-2(-9+1)#
#16=18-2#
#16=16# (correct)
