a − 2 + 3 = −2
Combine like terms.
-2 + 3 = 3 - 2 = 1
a + 1 = -2
Subtract 1 from both sides.
-2 - 1 = -3
a = -3
------------------------------
You can check your work by substituting -3 in for a.
-3 - 2 + 3 = -2
-3 - 2 = -5
-5 + 3 = -2
-2 = -2
Check. Both sides are equal, so a = -3
a - 2 + 3 = -2 You combine like terms -2+3 = 1
a+1=-2 you sub 1 from both sides
a=-3
a-(2+3)= -2
a-(5)= -2
a=3 because 5 take 3 is -2
Hope I helped :)
a= -7
