#x = 8#

Explanation:

#( 2x + 10 ) - ( 8x +48 ) = 10#

#2x + 10 - 8x + 48 = 10#

#-6x + 58 = 10#

#6x = 58 - 10#

#6x = 48#

Therefore,

#x = 48/6#

#x = 8#

#x=8#

Explanation:

#"distribute the brackets on left side of equation"#

#2x+10-8x+48=10#

#rArr-6x+58=10#

#"subtract 58 from both sides"#

#=-6xcancel(+58)cancel(-58)=10-58#

#rArr-6x=-48#

#"divide both sides by "-6#

#(cancel(-6) x)/cancel(-6)=(-48)/(-6)#

#rArrx=8#

#color(blue)"As a check"#

Substitute this value into the eft side of the equation and if equal to the right side then it is the solution.

#2(8+5)-8(8-6)=26-16=10#

#rArrx=8" is the solution"#
