First divide 15 by 3 to find xx= 15/3 = 5Now use x to find yx +y = 7 substitue x. 5+y=7y= 7-5= 2Now you know x=5 and y=2 use this to calculate the answer, remembering to do the sum within the brackets fir...

Because we're told that x = 6, we can just rewrite the original equation but replace the x with a 6. So:
y = 15 + 5(6 + 2)
6 + 2 = 8, so we can rewrite this again as:
y = 15 + 5(8)
5(8...
