-3%283x%2B15%29-%2810%2Bx%29=35+.....first eliminate parentheses
-3%2A3x-3%2A15-10-x=35+
-9x-45-10-x=35+
-10x-55=35+.........move -10x to the right and 35 to the left
-35-55=10x+
-90=10x+
x=-90%2F10
x=-9

-3(3x+15)-(10+x)=35
-9x - 45 - 10 -x = 35
-10x -55 = 35
Add 55 to both sides of the EQ
-10x = 90
x = -9
AND
-3(-12) - 1 = 36 - 1 = 35 CHECKS!
