Answer:
x= 28
Step-by-step explanation:
10/70=4/x
First, you can distribute the -2 to 1 - 7n
the new equation is 5n + 34 = -2 + 14n
then, you can add 2 to both sides to cancel the -2 on the right
now you have 5n + 36 = 14n
after this, you add -5n to both sides, again, to cancel the 5n on the left
you are left with 34 = 9n
lastly, divide both sides by 9 to find the value of n, which is 4.
Just divide it by two. That just means half of 526, which is 263.
3/4 + 8/9
= (3*9)+(4*8) / (4*9)
= 27+32 / 36
= 59/36
= 1 23/36
