The number is 11. 63
Algebraic expressions are mathematical expressions comprised of constants and variables.
These expressions combines numbers, symbols, variables and mathematical operators such as addition, subtraction, multiplication, etc
From the information, let the number be x
2( x + (-6)) = x - 3/ 8
expand the bracket
2x - 12 = 8x - 3 /8
cross multiply
8 ( 2x - 12) = 8x - 3
expand the bracket
16x - 96 = 8x - 3
collect like terms
16x - 8x = -3 + 96
8x = 93
Make 'x' the subject
x = 93/ 8
x = 11. 63
The number is 11. 63
Thus, the number is 11. 63
