5x + 4y = 32 ⇒ 45x + 36y = 288
9x -  1y = 33 ⇒ <u>45x -    5y = 165</u>
                                    <u>41y</u> = <u>123</u>
                                     41      41
                                        y = 3
                            5x + 4(3) = 32
                              5x + 12 = 32
                               <u>    - 12  - 12</u>
                                      <u>5x</u> = <u>20</u>
                                       5      5
                                        x = 4
                                  (x, y) = (4, 3)

gregori [183]

How could you solve for x in the problem 3x+7=-x-1
lukranit [14]

Hello there!

3x+7=-x-1\\

Explanation:

↓↓↓↓↓↓↓↓↓↓↓↓

First you had to subtract by 7 from both sides of the equation.

3x+7-7=-x-1-7

Simplify

3x=-x-8

Then you add by x from both sides of the equation.

3x+x=-x-8+x

Simplify

4x=-8

Divide by 4 from both sides of the equation.

\frac{4x}{4}=\frac{-8}{4}

Simplify it should be the correct answer.

x=-2

Answer⇒⇒⇒x=-2

Hope this helps!

Thank you for posting your question at here on Brainly.

Have a great day!

Identify the equation or inequality of the graph
marishachu [46]

Answer:

<h2>3x - 2y = 6</h2>

Step-by-step explanation:

By looking at the graph we deduce :

Slope = 3/2

y-intercept = -3

then the line‘s equation is : y = 3/2x - 3

multiply both sides by 2 → 2y = 3x - 6

then 3x - 2y = 6
