first one- 52+76+120+X=360 (52+76)+120+X=360 (128+120)+X=360. make sure to subtract 248+X=360. 248 to both sides -248. -248. keep it equal man ___________ X=112
2. 4X+18+90+34+12X+6=360. make sure you 16X+148=360. add like signs
16x+148=360. subtract 148 -148. -148. from both sides __________ 16X=212. divide the 16 from both ___. __. sides to cancel the 16 16. 16.
X=13.25. check
3. 84+2Y+5Y+6+2Y+9Y+22 add like terms 18Y+112=360
18Y+112=360 subtract 112 from both -112. -112. sides __________ 18Y=248. divide both sides by 18 __. __. to cancel the 18 18. 18
