let's see what to do buddy....

Step-by-step explanation:

3( \frac{7}{5}x + 4) - 2( \frac{3}{2} -  \frac{5}{4}x) \\  \\  =  \frac{21}{5}x + 12  - 3 +  \frac{5}{2}x \\  \\  =  \frac{(21 \times 2) + (5 \times 5)}{10}  x + 9 =  \\  \\  \frac{42 + 25}{10} x + 9 =  \frac{67}{10}x + 9 = 6.7x + 9

Which equation matches the statement below?
kvasek [131]

Answer:

3(n-5)=2n+16

Step-by-step explanation:

3 lots of 'n' <em>and </em>5 means 3 times both values so these values are put into a bracket with a common multiplier (ie. the 3)

3(5 - n)

16 more than 2 lots of 'n' means that n has to be doubled. n + n = 2n. add 16 to this and we have

2n + 16

if these values are both equal (hence why they are in an equation) then all that is needed is for them to be set equal alongside each other.

3(n-5) = 2n+16
