Solve the pair of simultaneous equations and leave the answer as a fraction in

Elena-2011 [213]

Answer:

x = 11/3 = 3 2/3

y = 13/3 = 4 1/3

Step-by-step explanation:

Here, we want to solve the system of equations simultaneously

x + y = 8

2x -3 = y

From the second equation, we have an equation for y

we can simply proceed to substitute this into the first equation

x + 2x - 3 = 8

3x - 3 = 8

3x = 8 + 3

3x = 11

x = 11/3

Recall;

y = 2x - 3

y = 2(11/3) - 3

y = 22/3 - 3

y = (22-3(3))/3

y = (22-9)/3 = 13/3

Uhhhhhhh i dont understand tis

Answers:

f) hard working. Think of "industry" or "industrial" to help remember.
b) state of disorder. Mayhem is effectively chaos.
e) expressions of sorrow. For example, you would give lamentations at a funeral.
i) gridlock or standstill. Example: "Congress is at an impasse on passing a new spending bill". You can think of it like saying "it's not possible to pass or get through".
a) A long angry rant or speech. I'm not sure what trick you can use to remember this, but the term "harangue" sounds negative which seems to be fitting with the angry rant/speech.
c) Overly concerned about small details. Usually you might hear it used in a way where someone mentions "not to be pedantic", they basically mean "not to nitpick at the fine details".
h) Terrible; extremely poor. Someone who is abominable has bad morals or values as a person. For instance, a murderer is someone who is abominable.
d) Characterized as having too high of an opinion of oneself. Someone with a big ego only thinks about themself and no one else. The tern narcissism also applies.
g) The effects of something. Specifically, repercussions are referred to as unintended consequences of an action.
j) The act of surrendering. I don't know of a useful trick to help remember this term.
