Please help me find the values of y and z .

y=120 and z=20

Step-by-step explanation:

bringing (5z-40)° in their vertically opposite side

5z-40=60[being the pair of corresponding angle]

or, 5z=60+40

or, 5z=100

z=20

again,

5z-40+y=180[sum of straight angle]

or, 5×20-40+y=180

or, 100-40+y=180

or, y=180-60

y=120

The equation is false

Step-by-step explanation:

10 - 9 x 24 = 8 x 6

Multiply

10 - 216 = 48

Add 216 to both sides of the equation

10 ≠ 244

False
