L.H.S.= R.H.S.
5+y=9 {we will shift 5 to R.H.S. to obtain the value of y}
y=9-5 {as 5 is positive it will become negative when shifted to R.H.S.}
y=4
therefore the value of y is 4.
CHECK!
5+4=9
9=9
9 plus 7 equals 144. Generally, x plus y = x(x+y).
I feel like I'm doing someone's homework! y/9 + 5 = 0 rearranging: y/9 = -5 y = -5 x 9 y = -45
The answer to the equation 9 plus 5 times 0 equals 45. This was taught in 5 grade math.
You zero out the variables in turn. Y = 9(0) + 5 Y = 5 ---------- 9X + 5 = 0 9X = - 5 X = - 5/9 Can use these points to graph line. ( - 5/9, 5)

y = -2/5

y+9=14 subtract 9 from each side to get y by itself y=5
x=4 y=5 9x+7y=?? Replace: 9(4)+7(5)= 71
9 plus 7 equals 144. Generally, x plus y = x(x+y).
Slope: -9
Both lines would be parallel to each but the y intercept would change from 5 to 9
x = y+3 x+2y = 9 => x = 9-2y y+3 = 9-2y 2y+y = 9-3 3y = 6 y = 2 and x = 5
I feel like I'm doing someone's homework! y/9 + 5 = 0 rearranging: y/9 = -5 y = -5 x 9 y = -45
9y + 5 = 0 (-5 on both sides)9y = -5 (/9 on both sides)y = -5/9
Y+7=9 equals 2+7=9.
