when you get this kind of exercise, you find need to find y or x in one of the exactions and fill it in in the other, however in this exercise the two y's are already given so all you need to do is replace the y in one of the exactions with the other exactions like this:

(keep in mind, you need to keep writing both of the exactions over again, otherwise you'll lose an exaction. and we'll need it later on)

y=-2x+6

y=3x-4

y=-2x+6

-2x+6=3x-4

y=-2x+6

-2x-3x=-4-6

y=-2x+6

-5x=-10

y=-2x+6

x= 2

and now replace the x in the first exaction with the x that we found:

y=-2(2)+6

x=2

y=-4+6

x=2

y=2

x=2

A taxi company charges a fixed hire fee (which is a whole number of dollars) plus a rate for each
vesna_86 [32]

Answer:

362 kilometre

Step-by-step explanation:

Let a be the total cost of a journey

let b represent the total distance of a journey

$1.75 is a fixed charge of a journey

the additional charge is $0.10 for b distance ,hence total of additional charge is $.10 multiplied by b i.e 0.1 b

a=1.75+0.1b

a =37.90

37.90=1.75+0.1b

0.1b=37.90-1.75

0.1 b=36.15

b=36.15 /0.10

b=361.5

b=362 kilometre

For the journey that cost 21.80

21.80=1.75+0.1 b

0.1 b=21.80-1.75

0.1 b=20.05

b=20.05 /0.1

b=200.5

b =201 kilometre

Solve for x. 3x+1/14=2x/8
Ludmilka [50]
It depends if it is
1. 3x+(1/14)=(2x)/8 or
2. (3x+1)/14=(2x)/8

if it is 1

1.
3x+(1/14)=2x/8
simplify 2x/8
2x/8=x/4
3x+(1/14)=x/4
find least common multiple of 14 and 4
factors of 14=2 and 7
factors of 4 are 2 and 2 so LCM=2 times 2 times 7=28
multiply both sides by 28
84x+2=7x
subtract 7x from both sides
77x+2=0
subtract 2 from both sides
77x=-2
divide both sides by 77
x=-2/77


2.
(3x+1)/14=2x/8
simpify 2x/8
2x/8=x/4
(3x+1)/14=x/4
find least common multiple of 14 and 4
factors of 14=2 and 7
factors of 4 are 2 and 2 so LCM=2 times 2 times 7=28
multiply both sides by 28
(2)(3x+1)=7x
distribute
6x+2=7x
subtract 6x from both sides
2=x
