Step-by-step explanation:
Hope this helps!❆
You will make 1224-1000=224
then you will divide 224 by two it will be 112
you will add 112 to the less one
112+1000=1112
Account 1 : y = 2500(1.078)x
account 2 : y = 2500 + 300x
after the second year a1 exceeds a2
after 2 years, a1 = 5390
after 2 years , a2 = 3100
2+4z-18
change it so it's an equation
2+4z-18=0
then get 4z alone on one side by subtracting 4z from both sides
2-18=-4z
-16= -4z
divide both sides by -4
a negative divided by a negative becomes positive
4 =z
plug it in
2+4(4)-18
4x4 is 16
2+16-18=0
0=0
the same can be done for the second one 2+k-8
make it 2+k-8=0
move the k to get it alone so subtract k from both sides
2-8=-1k
-6 = -1K
you can divide by K to make K=6
plug in 2+6-8=0
0=0
