Step-by-step explanation:
Apply these rules to solve:
• Angles on a straight line add up to 180 degrees.
• Angles in a triangle add up to 180 degrees.
• Opposite angles in a parallelogram are equal.
• Angles in a quadrilateral add up to 360 degrees.
Answer:
Step-by-step explanation: Step 1: Simplify both sides of the equation.
3(y+8)=36
(3)(y)+(3)(8)=36(Distribute)
3y+24=36
Step 2: Subtract 24 from both sides.
3y+24−24=36−24
3y=12
Step 3: Divide both sides by 3.
3y/3=12/3
y=4
