Explanation:
Isolate - 0.3x on the left side by subtracting 5.19 from both sides of the equation.
#-0.3xcancel(+5.19)cancel(-5.19)=-2.31-5.19#
#rArr-0.3x=-7.5# To solve for x, divide both sides by - 0.3
#(cancel(-0.3) x)/cancel(-0.3)=(-7.5)/(-0.3)#
#rArrx=25#
#color(blue)"As a check"# Substitute this value into the left side and if equal to the right side then it is the solution.
#(-0.3xx25)+5.19=-7.5+5.19=-2.31#
#rArrx=25" is the solution"#
