Answer:
adding both equations
4x+9y=5
-4x+7y=11
+ + =+
________
0 +16y=16
y=1
putting the value of y in first eqn
4x+9×1=5
4x=5-9
4x=-4
x=-1
so the x is -1 and y is 1
Answer:
-36
Step-by-step explanation:
let the number be x
expressing the question mathematically,
x / (-3) = 12 (multiply both sides by -3
x = 12 (-3)
x = -36
