Answer:
x=5
Step-by-step explanation:
-3x+7=-8
Bring 7 to the other side, it becomes negative
-3x=-8-7
Signs are same on rhs so u add
-3x = -8+-7= -15
Bring -3 to the other side n divide
therefore,
x=-15/-3
= +5 (two negatives become positive)
Hope it helps!
x = 5
<u>→Subtract 7 from both sides:</u>
-3x + 7 = -8
-3x = -15
<u>→Divide both sides by -3:</u>
28
21/2 * 8/3 = 28
