Which values of x and y satisfy 2x − y = 7 and 3x − 2y = 5 simultaneously?
photoshop1234 [79]
To solve problems like this you can either graph or solve mathematically. To do the ladder we need to solve for one variable at a time. So lets cancel one variable out.
Multiply equation 1 by 2
This will give 4x-2y=14
Now we can get rid of y by subtracting 2 from 1
This will give x=9
Plug back in to either equation, i will use equation 2
3(9)-2y=5 simplify
-2y=-22 solve
Y=11

Use Cramer's Rule to solve the following system: –2x – 6y = –26 5x + 2y = 13
andriy [413]
\bf \begin{cases}&#10;-2x-6y&=-26\\&#10;\quad 5x+2y&=13&#10;\end{cases}\stackrel{\textit{determinant of the coefficients}}{D=&#10;\begin{bmatrix}&#10;-2&-6\\5&2&#10;\end{bmatrix}}\implies (-4)-(-30)&#10;\\\\\\&#10;D=-4+30\implies \boxed{D=26}\\\\&#10;-------------------------------\\\\

\bf x=\cfrac{D_x}{D}\implies x=\cfrac{&#10;\begin{bmatrix}&#10;\boxed{-26}&-6\\\\ \boxed{13}&2&#10;\end{bmatrix}}{D}\implies x=\cfrac{(-52)-(-78)}{26}&#10;\\\\\\&#10;x=\cfrac{-52+78}{26}\implies x=\cfrac{26}{26}\implies \boxed{x=1}\\\\&#10;-------------------------------\\\\&#10;y=\cfrac{D_y}{D}\implies y=\cfrac{&#10;\begin{bmatrix}&#10;-2&\boxed{-26}\\\\ 5&\boxed{13}&#10;\end{bmatrix}}{D}\implies y=\cfrac{(-26)-(-130)}{26}&#10;\\\\\\&#10;y=\cfrac{-26+130}{26}\implies y=\cfrac{104}{26}\implies \boxed{y=4}

Simultaneously x-2y=0 40-y=14​
harkovskaia [24]

Answer:

x = 52, y = 26

Step-by-step explanation:

x - 2y = 0

40 - y = 14​

(40 - 40) - y = 14​ - 40

- y = -26

y = 26

x - 2(26) = 0

x - 52 = 0

x (- 52 + 52) = 0 + 52

x = 52
