Which ordered pairs make the equation true? 3x+2y=−7 Select each correct answer. (3, −8)

Nikolay [14]

<h2>SOLVING</h2>

$\Large\maltese\underline{\textsf{A. What is Asked}}$

Which ordered pairs make the equation $\bf{3x+2y=-7}$ true? Select all that apply. 3 options are given

$\Large\maltese\underline{\textsf{B. This problem has been solved!}}$

We can tell which ordered pairs make equations true by plugging in the coordinates.

$\mathbb{ORDERED\;PAIR\;NUMBER\;ONE}$

$\bf{3(3)+2(-8)=-7}$ | simplify

$\bf{9-16=-7}$ |simplify

$\bf{-7\equiv-7}$ | this one checks

$\mathbb{ORDERED\;PAIR\;NUMBER\;TWO}$

$\bf{3(-2)+2(-1)=-7}$ | simplify

$\bf{-6-2=-7}$ | simplify

$\bf{-8\neq-7}$ | this one does <em>not </em>check

$\mathbb{ORDERED\;PAIR\;NUMBER\;THREE}$

$\bf{3(1)+2(-4)=-7}$ | simplify

$\bf{3-8=-7}$ | simplify

$\bf{-5\ne-7}$ | this one does <em>not</em> check

$\rule{300}{1.7}$

$\bf{Result:}$

$\bf{=The\;First\;Option$

$\boxed{\bf{aesthetic \not101}}$

Which system of equations is equivalent to the system of equations shown?

Ivanshal [37]

<span>I can solve for x and y
A) 2x - 4y = 12
A) 2x = 4y + 12
A) x = 2y + 6
Substituting into B
B) 3* (2y +6) - 5y = 20
B) 6y + 18 -5y = 20
B) y = 2
B) x = 10

Help ASAp peaseeeeeeeeee

Answer:

7/6

Step-by-step explanation:

$\frac{ \frac{x}{4} + \frac{x}{3} }{ \frac{x}{2} } = \frac{x( \frac{1}{4} + \frac{1}{3} )}{ x(\frac{1}{2}) } \\ = \frac{ \frac{1}{4} + \frac{1}{3} }{ \frac{1}{2} } \\ = \frac{14}{12} = \frac{7}{6}$
