Just subisute values that will work
one easy way is to make one sides equal to only one of the placeholders, like y, and then lug in values in for x exg
x+2y=3
subtract x from both sides
2y=3-x
divideb bith sides by 2
y=-1/2x+3
subsitute valudes for x and get values for y
if x=2 then
y=-1/2(2)+3
y==-1+3
y=2
when x=2, y=2
when y=0 then y=3

Answer:
bill = 6
hoang = 14
Step-by-step explanation:
the following equations can be formed from the question
H = 8 + b eqn 1
h - 2 = 2b eqn 2
make h the subject of the formula in eqn 2
h = 2b + 2
2b + 2 = 8 + b
collect like terms
2b - b = 8 - 2
b = 6
h = 8 + 6 = 14
