5x-13x+6=0 5x-13x=-6 -8x=-6 -8x/-8=-6/-8 x = 3/4
Given 6x + (7x-8) = -5 6x + 7x - 8 = -5 ==> 13x = 3 therefore, x = 3/13
x = 3Solution:3x + -1 = 83x = 8 + 13x = 9x = 9/3x = 3Check:3(3) + -1 = 89 + -1 = 88 = 8
Yes, -8 plus plus 3 equals -5. The "plus plus" is equivalent to a positive sign, so -8 plus (+3) equals -5.
89
5x-13x+6=0 5x-13x=-6 -8x=-6 -8x/-8=-6/-8 x = 3/4
Since 7x + 13x +2x + 8 is an expression (there is no equal sign), there is no answer as to what x equals. However, this expression can be simplified to 22x + 8.
Add the coefficients of the variable term X. 2 + 3 + 8 = 13X
Given 6x + (7x-8) = -5 6x + 7x - 8 = -5 ==> 13x = 3 therefore, x = 3/13
