Question

Find X and Y diagram below which two do i add

Answer 1

the opposite sides of a parallelogram are equal
so
ON = LM
and ON = NM

replace these lines by the given values and solve the system of eqquations

Answer 2

x = 12?

Answer 3

ON = LM

8x - 8 = 7x + 4
8x - 8 + 8 = 7x + 4 + 8
8x = 7x + 12
8x - 7x = 7x + 12 - 7x
x = 12

NM = OL

x - 5 = 3y - 6
x - 5 + 5 = 3y - 6 + 5
x = 3y -1

8(3y - 1) - 8 = 7(3y - 6) + 4
24y - 8 - 8 = 21y - 42 + 4
24y - 16 = 21y - 38
24y - 16 + 16 = 21y - 38 + 16
24y = 21y - 22
24y - 21y = 21y - 22 - 21y
3y = -22
y = 7. 3

Answer 4

Answer 5

having found x = 3y - 1
and x = 12
all you need do is plug in x = 12 then solve for y

12 = 3y - 1
3y = 13
y = 13/3 = 4.33

Answer 6

Ok?

Answer 7

yes one minute

Answer 8

do then do i plug in the numbers ? @welshfella
