$-1.5(2.1x - 4)=0.8x - 4.7x$

Answer:

$x = -5$

Explanation:

Step1: Expand the left - hand side

$-1.5\times2.1x+(-1.5)\times(-4)=0.8x - 4.7x$ $-3.15x + 6=0.8x - 4.7x$

Step2: Combine like terms on the right - hand side

$-3.15x + 6=-3.9x$

Step3: Add $3.9x$ to both sides

$-3.15x+3.9x + 6=-3.9x+3.9x$ $0.75x+6 = 0$

Step4: Subtract 6 from both sides

$0.75x+6 - 6=0 - 6$ $0.75x=-6$

Step5: Solve for $x$

$x=\frac{-6}{0.75}=-5$
