i would start by distributing the (-1) through the (5-3x)
2x-5+3x=4x+2 (combine like terms) 5x-5=4x+2 (move the x to the left side of the equation by subtraction) x-5=2 (then of course we isolate the x by adding the 5 to the right side) x=7
then you can check your work by replacing all of the x's with 7 2(7)-1(5-3(7))=4(7)+2 14-1(-16)=28+2 14+16=30 30=30
