Question

.

Answer 1

we have equations

\[-4.5x-2y=-12.5 \]
and

\[3.25x-y=-0.75\]

Answer 2

can you solve first equation for x ?

Answer 3

okay let's solve it..
solving an equation for x means finding the value of equation in terms of x

let's go first equation and solve it for x

by adding 2y on n=both sides of equation first what we get?

Answer 4

i meant by adding 2y on both sides of equation first what we get?

Answer 5

that's right ad let's divide both sides by 4.5 what we get??

Answer 6

sorry by -4.5

we get -2.78-0.44=x put this value of x in eqution 2 and solve it for y

Answer 7

sorry by -4.5 we get -2.78-0.44y=x put this value of x in equation 2 and solve it for y

Answer 8

check you calculations

Answer 9

okie don't freak out its k ... just put values of x we have obtained in second equation what ou would get??

Answer 10

just plug this values of x in equation 2
