22 x 0.35 = 7.7
132 (6 x 22) 66 (6 x 11) ( 22 x 3)
6
To solve 6 x 22 using the grid method, you first break down 22 into its components: 20 and 2. Then, create a grid with one row for 6 and columns for 20 and 2. Multiply: 6 x 20 equals 120, and 6 x 2 equals 12. Finally, add the two products together: 120 + 12 equals 132, so 6 x 22 equals 132.

22+2x = 37+6+x 2x-x = 37+6-22 x = 21
X +13 equals 22, X equals nine
Variables are just letters to solve for the unknowns. ex of a variable: 4x-6 = 16 x is a variable in this case, so we solve for it 4x = 22 x = 11/2
-6 = x + 6 Solve for x -6 - 6 = x x = -12
To solve this equation we have to isolate and solve for x. So: 2x-6= x+5 +6 +6 2x = x+11 -x -x x = 11 So x=11.
22 x 0.35 = 7.7
132 (6 x 22) 66 (6 x 11) ( 22 x 3)
6x-4 = 18 6x = 18+4 6x = 22 x = 22/6 = 3 and 2/3
X + Y = 22 X - Y = 4 add equations: 2X = 26 solve X X = 13 solve Y Y = 9
24x = 6 x = 6/24 x = 1/4
3/5x + 22 = 28 To solve this: Subtract 22 from both sides: 3/5x = 6 Multiply by 5x: 3 = 6*5x Divide by 6: 3/6 = 5x Divide by 5: (3/6)/5 = x Work it out: 3/6 = 0.5 0.5/5 = 0.1 x = 0.1
X is 6
