Let the number be x: 7x-6 = -20 7x = -20+6 7x = -14 x = -2
7x = 6 x = 6/7
11
7x-4=x+2 7x=x+2+4 7x=x+6 7x-x=6 6x=6 X=1
7x+y=6
7x / 2 = 3 7x=2(3) 7x=6 x=6/7 The answer is x=6/7
Let the number be x: 7x-6 = -20 7x = -20+6 7x = -14 x = -2
The expression is: 7x-6
7x = 6 x = 6/7
11
-7x + 6 + 7x - 2 = 4
4/x times 6/21 = 24/21x simplify (divide top and bottom by 3) = 8/7x 8 over 7x
let the number be x. ∴ 6 + 4x = 7x ∴ 6 = 7x - 4x ∴ 6 = 3x ∴ x = 6/3 ∴ x = 2 Ans. The number is 2.
(4)(2)+7x-28+7x-27x-6.This expression cannot be simplified further nor solved (because it is not equal to anything).
i will simplify: 5 times x times 6= 7 times x - 16
x2 + 7x = 2x2 + 6 x2 - 2x2 + 7x = 6 -x2 +7x - 6 = 0 or alternatively x2 - 7x + 6 = 0
Here is the work for that problem. 7x+6= 41 7x=41-6 (subtracting 6 from both sides) 7x=35 x=5
