Answer:
x = -12
Step-by-step explanation:
Step 1: Isolate x
1/4x + x = -12 - 3
Step 2: Combine like terms
5/4x = -15
Step 3: Simplify
x = (-15)(4/5)
x = -12
Answer: -12
Step-by-step explanation:−1 /4 x−12=x+3
Step 1: Subtract x from both sides.
−1 /4 x−12−x=x+3−x
−5 /4 x−12=3
Step 2: Add 12 to both sides.
−5 /4 x−12+12=3+12
−5 /4 x=15
Step 3: Multiply both sides by 4/(-5).
( 4 /−5 )*( −5 /4 x)=( 4 /−5 )*(15)
x=−12
