x - y = 52x + y = 7 (use the substitution method)y = x - 52x + y = 7 (substitute x - 5 for y into the second equation)2x + y = 72x + x - 5 = 73x = 12x = 4Thus x = 4 satisfies both the equations of the system.
Y=52X Your answer is Y. "A number" is X.
x = 0.52 because: 52x + 3 = 30 52x = 30 - 3 52x = 27 x = 27/52 x = 0.52 ( to two decimal places)
-52x + 3 = 7 -52x + 3 = 7 -3 -3 -52x = 4 /52 /52 -x = 1/13 /-1 /-1 x = -1/13
52x - 7 = 33 - 36x + 4 52x + 36x = 33 + 7 + 4 88x = 44 x = 1/2
(2x - 10) + 7 = 52x - 3 = 52x = 8x = 4
"less than AND equals to" is an impossible condition.
It is an equation and the value of x is -3
a = 3 and y = 0
Assuming you meant 52x+3=30 52x=30-3 52x=27 x=27/52 or approximately 0.51923
y=9x=3it equals ......y= 3.334
x equals y
