упростите выражение (35+х)-15, (432+b)-265, (a+636)-129,96-(m+48). 516-(216+X),444-(y+58) помогите плииззз

( 35 + х ) - 15  =  35 + х - 15 = ( 35 - 15) + х = 20 + х

( 432 + b ) - 265 = 432 + b - 265 = ( 432 - 265 ) + b = 167 + b

( a + 636 ) - 129 = a + 636 - 129 = a + ( 636 - 129 ) = a + 507

96 - ( m + 48 ) = 96 - m - 48 = ( 96 - 48 ) - m = 48 - m

516 - ( 216 + x ) = 516 - 216 - x = ( 516 - 216 ) - x = 300 - x

444 - ( y + 58 ) = 444 - y - 58 = ( 444 - 58 ) - y = 386 - y
