remember you can do ANYTHING to an equation as long as you do it to both sides
2(x+3)-5=5x+4
distribute 2 to x+3
2(x+3)=2x+6
now we have
2x+6-5=5x+4
combine like terms
2x+1=5x+4
minus 2x from both sides (subtraction property of equality)
2x-2x+1=5x-2x+4
addative inverse
0+1=3x+4
zero addition property
1=3x+4
minus 4 from both sides
1-4=3x+4-4
addative inverse
-3=3x+0
zero addition property
-3=3x
diide both sides by 3
-3/3=3x/3
multilicative inverse
-1=1x
one identity property of multiplication
-1=x
x=-1
