Jika k merupakan penyelesaian \(2(3x-5)+3=3(4x+2)-1\). Maka nilai \(3k+5\) sama dengan....

mencari nilai k = x

\(\begin{aligned} 2(3x-5)+3 &= 3(4x+2)-1 \\ 6x-10+3 &= 12x+6-1 \\ 6x-7 &= 12x+5 \\ 6x-12 &= 5+7 \\ -6x &= 12 \\ x &= \frac{12}{-6} \\ x &= -2 \end{aligned}\)

nilai 3k+5

\(\begin{aligned} 3k+5 &= 3(-2)+5 \\ &= -6+5 = -1 \end{aligned}\)
