(((x*3)/4)+8)-5 = y --------------------------------------------------------------------------------------------------- Assume the number is Y three times the number + 8 = 3Y + 8 1/4 th this quantity is (3Y + 8)/4 then 5 less this quantity = 5 - (3Y + 8)/4 Assume Y = 4 for example then the result is zero Assume Y = 8 for example then the result is -3 Assume Y = zero then the result is +3
The expression can be thus: 3x-3 whereas x is the unknown variable
4/7
If: 3x-8 = -14 then x = -2
Three less than twice x is 2x-3.Two more than the quantity 3 times x is 3x + 2.The product of these is (2x-3)(3x+2), which can also be written as:(6x2 - 5x - 6)
