2x-10=3x-40
bring -10 to the right and 3x to the left:
2x-3x=-40+10
-x=-30
multiply both sides with a negative:
x=30

2x-10=3x-40 isolate x by:
2x-3x=10-40 bringing terms with x to one side
-1x=-30 then change the signs to positive
1x=30
so x=30

2x-10=3x-40
subtract 2x from both sides
-10=x-40
add 40 to both sides
30=x
x=30

Collect like terms on either side:
3x-2x = 40-10
x = 30

2x -10=3x-40 subtract 2x on b.s
2x-2x-10=3x-2x-40
-10=x-40
now10 adding on b.s
10-10=x+10-40
0=x-30
x=30
