Your question seem to me non-understandable. Are they adding up together ?
or multiplying ?
Answer:
t=12
Step-by-step explanation:
Step 1: Subtract t from both sides.
−t+5−t=t−19−t
−2t+5=−19
Step 2: Subtract 5 from both sides.
−2t+5−5=−19−5
−2t=−24
Step 3: Divide both sides by -2.
−2t−2=−24−2
You will get x as 56 and angle ABC as 51°
