18 x 27 = (18 x 20) + (18 x 7)
7/9 x 18 = 147/9 of 18 is 14.
6 x 3 = 18 7 x 3 = 21 therefore 6 to 7 = 18 to 21

given is that 4x+3y=6(3x+3y)=7 i.e., 6(3x+3y)=7 &&& 4x+3y=7 ---------------(1) 3x+3y=7/6 x+y=7/18 _________(2) multiply eqn(2) by 4 4x+4y=28/18 -------------------------(3) (3)-(1) 4x+3y-4x-4y=7-(28/18) y= -98/18 substitute y in eqn(2) x-98/18=7/18 x=7/18+98/18 x=105/18. therefore x=105/18 : y= -98/18
2x9=18 so x-7 is 9, x is 16
If you mean: 2(x-7) =18 then the value of x works out as 16
18 x 27 = (18 x 20) + (18 x 7)
7/9 x 18 = 147/9 of 18 is 14.
X - 7 = 11 X = 11+7 therefore X = 18 18 minus 7 equals 11.
6 x 3 = 18 7 x 3 = 21 therefore 6 to 7 = 18 to 21
18 x 7 = 126 square feet
x + 7 - 2x = 18 Combine the terms containing x: 7 - x = 18 Subtract 7 from both sides: -x = 11 Multiply both sides by -1 (or change the sign on both sides): x = -11

7/8 of 18 = (7 x 18)/8 = 126/8 = 15.75 or 1/8 of 18 = 18/8 = 2.25 2.25 x 7 = 15.75
x-7+7=11+7 x=11+7 x=18
7 x 18 = 126
