If ba-cd =b which expression represents "a"?A. b-cd/bB. b+cd/bC. b/b-cdD. b/b+cd

navik [9.2K]

Isolating the variable 'a' in the expression, we have:

$\begin{gathered} ba-cd=b \\ ba=b+cd \\ a=\frac{b+cd}{b} \end{gathered}$

So the correct option is B.

Find the X COORDINATE OF THE intersection of 9x - 6y = 12 and 3x + 2y =8

yaroslaw [1]

Answer: $x=2$

Step-by-step explanation:

Given a System of linear equations, the solution of the system is the point $(x,y)$ in which the lines intersect, where "x" is the x-coordinate and "y" is the y-coordinate.

Having the following System of equations:

$\left \{ {{9x - 6y = 12} \atop {3x + 2y =8}} \right.$

You can use the Elimination method to find the value of "x":

-Multiply the second equation by 3.

- Add the equations.

- Solve for "x".

Then, you get:

$\left \{ {{9x - 6y = 12} \atop {9x +6y =24}} \right.\\.......................\\18x=36\\\\x=\frac{36}{18}\\\\x=2$
