Solve: + 12x = 9<br> Ox=3/5 :: 6<br> O x= 6 745<br> O=-6+ 745<br> O *=-6_315
Alex_Xolod [135]

Answer:

x =  \frac{3}{4}

Step-by-step explanation:

12x = 9

Divide both sides by 12:

\frac{12x}{12}  =  \frac{9}{12}

Simplify the fraction:

x =  \frac{9}{12}

Find the greatest common factor of the numerator and denominator:

x =  \frac{3.3}{4.3}

Factor out and cancel the greatest common factor:

x =  \frac{3}{4}

-2x - y = -9<br><br>5x -2y = 18<br>Solve as a whole number
nexus9112 [7]

Answer:

x = 4, y = 1

(4, 1)

Step-by-step explanation:

-2x - y = -9

5x -2y = 18

-2x - y = -9

+2x     +2x

-y = 2x - 9

/-1    /-1

y = -2x + 9

5x -2y = 18

5x - 2(-2x + 9) = 18

5x + 4x - 18 = 18

9x - 18 = 18

    + 18   + 18

9x = 36

/9  /9

x = 4

Now, we solve for y:

-2(4) - y = -9

-8 - y = -9

+ 8     +8

-y = -1

/-1  /-1

y = 1

(x, y) -> (4, 1)

Hope this helps!
