OpenStudy (welshfella):

For the first one divide both sides by 1/2 x = 9 / (1/2)

OpenStudy (johan14th):

1/2*x =9 is the same as x/2 =9 therefore to cancel the division we can multiply by 2 on both sides x = 9*2

OpenStudy (welshfella):

for the second multiply both sides by 4 x = 2 1/4 * 4 = (9/4) * 4

OpenStudy (welshfella):

18 is correct for the first one

OpenStudy (welshfella):

???

OpenStudy (welshfella):

no number 2 is |dw:1449768454886:dw|

OpenStudy (welshfella):

with this we can cancel the 4 Yes 9 is correct

OpenStudy (welshfella):

or we could multiply 4*9 = 36 then 36 divided by 4 = 9

OpenStudy (welshfella):

No 1 answer is 18 NO. 2 answer is 9 yw

OpenStudy (anonymous):

so X. X/4 = 2 1/4 = 9 and for X. 1/2 * X = 9 = 18

OpenStudy (anonymous):
