MArishka [77]

7x = 3y - 13       Divide both sides by 7

x = 3/7y - 13/7

Hello hope your day is well i really need help with this expand question 4(a+5)-2(a-5)
BARSIC [14]

Answer:

2a + 30

Step-by-step explanation:

break it down so it is 4(a+5)

then work out -2(a-5)

so 4 x a then 4 x 5 which gives 4a + 20

then -2 x a then -2 x -5 which gives -2a + 10

then when you have 4a + 20 -2a + 10

do 4a - 2a which is 2a

do 20 + 10 which is 30

so the answer comes to 2a + 30

if anything doesnt seem right just comment and i will correct

hope this helps :)
