4s+4=9 4s=9-4 4s=5 divide both sides by 4 s=5\4
b-3+6-2b collect like terms as follows b-2b-3+6 -b+3

solve the following equation 2x + 12= 4x
First of all, collect like terms by bringing numbers with letters to one side of the equal sign as follows: 12=4x-2x Note that as 2x crosses the equal sign, its sign changes. Before crossing the equal sign 2x had a positive sign but after crossing the equal sign, it's now negative. 12=2x To find the value of x, divide both sides by 2 Therefore x=6
