16x + 40y.....GCF is 8
8(2x + 5y) <==
13-4x=1-x
13=4x+x=1-x+x
13-3x=1
13-1-3x=1-1
12-3x=0
12=3x
12/3=3x/3
4=x
Therefore, x=4
2x = Twice your age
200 = Two hundred less
> -1 = more than negative
With the information given, your equation would be:
200-2x>-1
All you have to do here is combine like terms.
5x + 9x = 14x
.5 - 2.5 = -2
14x - 2
Answer:
x=5 and y=-2
Step-by-step explanation:
3x+5y=5
-(7x+5y=25)
-4x=-20
x=5
plug 5 into one of the equations. 3(5)+5y=5
y= -2
