#-70 = -2p + 4(-19/6p - 17/6)#
Solving the bracket first!
#-70 = -2p + cancel(4)^2(-19/cancel(6)_3p - 17/cancel(6)_3)#
#-70 = -2p + 2(-19/3p - 17/3)#
#-70 = -2p -38/3p - 34/3#
Multiply through with their LCM
#-70/1 = -2p/1 -38/3p - 34/3#
LCM = 3
#3(-70/1) = 3(-2p/1) -cancel3(38/cancel3p) - cancel3(34/cancel3)#
#3(-70) = 3(-2p) - 38p -34#
Simplifying..
#-210 = -6p - 38p - 34#
#-210 = -44p - 34#
Collect like terms..
#-210 + 34 = -44p#
#-176 = -44p#
Divide both sides by #color(red)(-44)#
#-176/color(red)(-44) = (-44p)/color(red)(-44)#
#cancel(-176)^4/cancel(-44)_1 = cancel(-44p)/cancel(-44)#
#4/1 = p#
#rArr p = 4#
