6) The number of sweets that tolu had is; 8 sweets

7) The number of sweets that Ogechi had is; 10 sweets

8) The number of sweets that Tamuno had is; 12 sweets

9) The number of sweets that Tamuno must give Tolu for them to have equal number is; 2 sweets

10) If Tolu gave four sweets to Tamuno, then Tamuno would have 4 times more sweets than Tolu

<h3>How to solve Algebra Word Problems?</h3>

Let the number of sweets that tolu had be x

Let the number of sweets that Ogechi had be y

Let the number of sweets that Tamuno had be z.

Thus;

x + y = 18  -----(1)

y + z = 22  -----(2)

x + y + z = 30   ------(3)

Substitute 22 for (y + z) in eq 3 to get;

x + 22 = 30

x = 30 - 22

x = 8

Substitute 18 for (x + y) in eq 3 to get;

18 + z = 30

z = 30 - 18

z = 12

y + z = 22

y + 12 = 22

y = 10
