Question

a = 1 + b,

b = 5 − 2a

Answer 1

so if a=1+b
then
b=5-2a=5-2(1+b)=5-2-2b=3-2b => b=3-2b
you can solve b=3-2b for b?

Answer 2

so we have b=3-2b
add 2b on both sides
3b=3
=> b=1

Answer 3

i came up with a=1+b
a+1=b

Answer 4

if b=1 then a=1+b=1+1=2

Answer 5

you check (a,b)=(2,1) this solution if you want
by plugging it into the set of equations and see if each equations holds
2=1+1
1=5-2(2)

Answer 6

what isn't right

Answer 7

my bad. tried to go too fast.

b=1 and a=2

myininaya is correct

Answer 8

tks am just not good at this
