Question

Use the Bar diagram tonight on the Quetion then solve for X

Answer 1

Ok so as we can see 3x=7+5=12 so now we know 7+5=12 we can divide by the 3x’s. So 12/3=4 so x =4
As for an equation. You could always do 3x=7+5 then to solve for it you just add the 7 and 5 then divide both sides by 3 to get x=4
