Question

2-(3x-8)=1 /5-(4x-9)=1/2​

Answer 1

Answer:

2-((3*x-8)/5)-(4*x)+9 = 1/2 // - 1/2

2-((3*x-8)/5)-(4*x)-(1/2)+9 = 0

2-((3*x-8)/5)-4*x-1/2+9 = 0

(-1*(3*x-8))/5-4*x-1/2+2+9 = 0

(-1*2*(3*x-8))/(2*5)+(-4*2*5*x)/(2*5)+(-1*5)/(2*5)+(5*2^2)/(2*5)+(2*5*9)/(2*5) = 0

5*2^2-1*2*(3*x-8)-4*2*5*x-1*5+2*5*9 = 0

16-46*x-5+20+90 = 0

11-46*x+20+90 = 0

31-46*x+90 = 0

121-46*x = 0

(121-46*x)/(2*5) = 0

(121-46*x)/(2*5) = 0 // * 2*5

121-46*x = 0

121-46*x = 0 // - 121

-46*x = -121 // : -46

x = -121/(-46)

x = 121/46

x = 121/46
