635/72=-5/2(-11/4+x)
distribute
635/72 = -5/2 * -11/4 - 5/2x
635/72 = 55/8 -5/2 x
multiply each side by 72 to clear the fractions
72*635/72 = 72*(55/8 - 5/2 x)
distribute
635 = 72* 55/8 - 72* 5/2 x
635 = 495 - 180x
subtract 495 from each side
140 = -180 x
divide by -180
-140/180 = x
-14/18 =x
-7/9 =x

Answer: x = 37 and y = 11
Explanation:
Let x be the bigger number
Let y be the smaller number
x + y = 48
But x is 7 less 4 times the smaller number.
=> x = 4y - 7
Substitute this value of x:
4y - 7 + y = 48
5y = 48 + 7
5y = 55
y = 11
Substitute the value of y in to the equation:
x + 11 = 48
x = 48 - 11
x = 37
Therefore, x = 37 and y = 11
Thirty three because I'm just smart like that so you should believe me entirely.
