Answer:
10x - 12y = 192
Step-by-step explanation:
Given the equation :
-5/8x + 3/4y = 12 - - - (1)
8x + 12y = 11 ___(2)
The equivalent form of the first equation which can eliminate the y term :
Multiply (1) by - 16 :
-5/8x * - 16 + 3/4y * - 16 = 12 * - 16
10x - 12y = 192
Hence, Adding the obtained equation and equation(2) will eliminate.
