Answer:
x = 14
Step-by-step explanation:
110 + 5x = 180
-110 -110
5x = 70
divide by 5 on both sides
x = 14
to find y add 70 + 40 + missing angle = 2y
missing angle is 70 because 70+40+70 = 180
so 2y = 110
y = 55

Answer:
All real numbers are solutions.
Step-by-step explanation:
Let's solve your equation step-by-step.
7x− 3 = − 3 + 7x
Step 1: Simplify both sides of the equation.
7x − 3 = −3 + 7x
7x + −3 = −3 + 7x
7x − 3 = 7x − 3
Step 2: Subtract 7x from both sides.
7x− 3 −7x = 7x −3 −7x
−3 = −3
Step 3: Add 3 to both sides.
−3 + 3 = −3 + 3
0 = 0
