#### Storyboard Text

• The product of 7 and a number, increased by 3, is equal to twice the number, subtracted from 39. Find the number.
• Mary can you please help me ﻿in my math homework, it's the last problem and I don't understand it
• ﻿First you have to write the multi step equation﻿
• Correct﻿
• That would be ﻿  7a + 3 = 2a - 39?
• ﻿First you have to pass the variables to the left side, and if it positive it'll change signs
• So it would be   5a + 3 = -39﻿
• Then you pass the 3 to the right and it becomes negative -3﻿
• Then were at     5a = -42﻿
• So now what do we do?﻿
• We isolate the variable?﻿
• ﻿So -42 divided by 5 is 8.4. (a= 8.4)
• Thanks a lot Mary, let's buy some candy﻿
