solve the equation -25+4y=35
-25+4y=35
Subtract 35
-25+4y-35=0
add 25 (to cancel out)
4y-35=25
add 35 (to cancel out)
4y=60
Divide by 4 to get y on its own
y=15
Hope this helps :)
to solve this we need to solve for y (try to leave y by itself)
-25+4y=35 to do this first you need to add (the opposite of subtraction) 25 on both sides (remember that the equation has to always be balanced) leaving you with 4y=60
after this the only function that attaches the 4 to the y is multiplication, so we do the opposite (division)
4y/4=60/4
y=15
now y is all by itself, meaning that we solved for y
hope this makes sense.
