Answer:
1) X+(-3/10) = -7/15
=> X-3/10 = -7/15
=> X = -7/15 + 3/10
=> X= 2(-7)+3(3)/30
=> X = -14+9/30
=> X = -1/6.
2) X+1/3 = -5
=> X = -5-1/3
=> X = -5/1 - 1/3
=> X = 3(-5)-1/3
=> X= -15-1 /3
=> X = -16/3
3) X+(-4) = -2/3
=> X = -2/3+4
=> X = -2/3+4/1
=> X = -2+3(4)/3
=> X = -2+12/3
=> X = 10/3
I Hope it helps you ☺️
