    Answer by JKismyhusbandbae:

    \mathrm{Expand\:}\left(-1.2x+9.8\right):\quad -1.2x+9.8\\2.3x+2.8=-1.2x+9.8\\\mathrm{Subtract\:}2.8\mathrm{\:from\:both\:sides}\\2.3x+2.8-2.8=-1.2x+9.8-2.8\\\mathrm{Simplify}\\2.3x=-1.2x+7\\\mathrm{Add\:}1.2x\mathrm{\:to\:both\:sides}\\2.3x+1.2x=-1.2x+7+1.2x\\Simplify\\3.5x=7\\\mathrm{Divide\:both\:sides\:by\:}3.5\\\frac{3.5x}{3.5}=\frac{7}{3.5}\\\mathrm{Simplify}\\x=2

    2.3x+2.8=−1.2x+9.8

    x=2

    Multiply both sides by 10:

    2.3x x 10+2.8 x 10=-1.2x 10+9.8 x10

    Refine:

    23x +28=-12x+98

    Subtract by 28:

    23x + 28-28=-12x+98-28

    Add 12x to both sides:

    23x+12x=-12x+70+12x

    Simplify:

    35x=70

    Divide by 35:

    35x/35=70/35

    Simplify:

    x=2

    Hope this helped!
