22 x 0.35 = 7.7
132 (6 x 22) 66 (6 x 11) ( 22 x 3)
9x + y = 22to solve for x-subtracy y from both sides --> 9x = 22 - ydivide by 9 on both sides --> x = (22/9) - (y/9)to solve for y - subtract 9x from both sides --> y = 22 - 9x
6
x+y=22 therefore y=22-x x*y=117 x*(22-x)=117 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
22 x 0.35 = 7.7
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
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.
132 (6 x 22) 66 (6 x 11) ( 22 x 3)
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
