22 x 0.35 = 7.7
132 (6 x 22) 66 (6 x 11) ( 22 x 3)
x+y=22 therefore y=22-x x*y=117 x*(22-x)=117 Solve for x.

To solve the equation 9x + y = 22, you need to isolate one of the variables. You can do this by either substituting a value for one variable and solving for the other, or by rearranging the equation to solve for one variable in terms of the other. For example, if you choose to solve for y, you would subtract 9x from both sides to get y = 22 - 9x. If you choose to solve for x, you would subtract y from both sides to get 9x = 22 - y, then divide by 9 to solve for x.
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
6x-4 = 18 6x = 18+4 6x = 22 x = 22/6 = 3 and 2/3
22 x 0.35 = 7.7
X + Y = 22 X - Y = 4 add equations: 2X = 26 solve X X = 13 solve Y Y = 9
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.

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
24x = 6 x = 6/24 x = 1/4
X is 6
