My Variables, equations and expressions

Slide 5

x = 5

x+ 27= 32        x2  + 52 = 104     X x 20 = 100    92+ 7x= 167

5 + 27 = 32      52 + 52 = 104      5 x 20 = 100    92+ 75 = 167

x - 24= 19         X x 32=  160      x4 + 12= 66     98x= 985

5 - 24 = 19        5 X 32 = 160      54 + 12 = 66    985= 985

x +19 = 24        x - 33= 28        6x + 32= 97

5 + 19 = 24       5 - 33 = 28       65 + 32 = 97

Slide 6

x +9 = -3                    y - 342 = 5

-6 + 9 = -3             337 - 342 = 5

y + 2 = 534              x + 98 = 124

532 + 2 = 534        26 + 98 = 124

z + 92 = 144

152 + 92 = 144

Slide 7

7 - x = -4                 z  - 119  = 13           6 x Z =  108            5 × z = 35          z x 8 = 32

7 - 11 = 4                 116 - 119 = 13         6 x 18 = 108            5 x 30 = 35       4 x 8 = 32

7 - 11 =  - 4             x + 1 = 45              6 × z = 102              x × 16 = 16          2 + x = -5

7 - 11 = -4             44 + 1 = 45            6 x  12 = 102           1  x  16 = 16         2  + 7 = -5

z × 5 = 65                14 + z = 30        1 + 15 = -23            108 ÷ x = 6       

60 x  5 = 65          14 +  16 = 30     1 + 15 = -23            108  ÷ 18 = 6

Slide 9

15 - 3 = x          x - 15 = 3

15 - 3 = 12        12 - 15 = 3

3x = 15               25 - x = 12

3 x 5 = 15          25 - 13 = 12

3 x 15 - 15 = x        9 - x =

3 x 15 - 15 = 35
