Question 1183534
<font face="Times New Roman" size="+2">
<pre>

(1)    6x +  4y = 15
(2)   12x -  3y = 10

Multiply (1) by 3 and (2) by 4:

(3)   18x + 12y = 45
(4)   48x - 12y = 40

Add the two equations eliminating the 'y' terms:

(5)   66x +  0y = 85  => 66x = 85

Solve for 'x'

(6)     x = 85/66
