• ﻿Today we will solve two-step equation with decimals!  ﻿
• ﻿-8.38v+10.71= 131.382
• ﻿﻿First you want to get rid of 10.71. So you want to subtract 10.71 itself.
• The 10.71 cancel out. So what you do to one side you do to the other.  131.328 -10.71
• ﻿-8.38v+10.71= 131.382 ﻿           -10.71= -10.71  __________________________________
• * Remember to line up the decimal ﻿
• ﻿
• ﻿After subtracting you got rid of the 10.71. You want the variable by it self.
• ﻿﻿-8.38v/-8.38 and 120.672/-8.38
• So you want the variable by itself,  you have to get rid of the -8.38. The problem we are solving says to multiply, so you will do the opposite and divide.  You have to divide  by itself and then do the other side.
• ﻿-8.38v+10.71= 131.382              -10.71= -10.71 ________________________________________    -8.38v          120.672    ____________            _____________ -8.38                     -8.38
