(3x + 30) / (2x-30) = 7 / 3 solution equation 3Q

(3x + 30) / (2x-30) = 7 / 3 solution equation 3Q


3(3X+30)=7(2X-30) 9X+900=14X-210 X=222



It is known that the solutions of the linear equation 4x-1 = 3 (X-2) and 2 / 1 of X-1 = 6x-2a with respect to X are the same


4x-1=3(x-2)
4X-3X=-6+1
X=-5;
Substituting x = - 5 into 2 / (x-1) = 6x-2a,
-1/3=-30-2a,
a=-89/6
