Let's solve your equation step-by-step.
5(a+3)+4=a−1
Step 1: Simplify both sides of the equation. 5(a+3)+4=a−1
Simplify: (Show steps) 5a+19=a−1
Step 2: Subtract a from both sides. 5a+19−a=a−1−a
4a+19=−1
Step 3: Subtract 19 from both sides. 4a+19−19=−1−19
4a=−20
Step 4: Divide both sides by 4. 4a4=−20
4a=−5
Answer:a=−5
