-2x+7 < 36 it like normal problem set < to normal.
so it will be like -2x + 7 = 36 minus 7 from both sides.
-2x= 29 and that is same as -2x < 29.
then divide -2 from both sides but when u do these aliigator mouth thing you change the sign when you divide or multiply negative. so x > 29/2 or x > 14 1/2

-2x + 7 < 36
-2x +7 - 7 < 36 - 7 (subtracting 7 from both sides)
-2x < 29
-2x / -2 > 29 / -2 (dividing both sides by -2; flip the sign)
x > 29 / -2

You need to use

The Multiplication Principle For Inequalities

-2x + 7 < 36 subtract 7 from both sides

-2x < 29 Divide both sides by -2, The symbol must be reversed!

x > -29/2 or x > -14.5



Note something to remember when you are multiplying or dividing this kind of problem by a negative number you must reverse the symbol.

Look in your text book at The Multiplication Principle For Inequalities to see what I mean.

I hope this helps you.

-2x <29
x>29/2

whenver you divide by negative you must ALWAYS flip the sign therefore it is > not <
