Question

Explain how to solve 6x+2y=14 and 5x-2y=8

Answer 1

x=6, y= 11

Explanation:

Simultaneous equations:

6x+2y=14 ----->1

5x-2y=8 ------>2

where 6x+2y=14 is equation 1 and 5x-2y=8 is equation 2.

Equation 1 minus Equation 2:

(6x+2y=14)-(5x-2y=8)=>x=6

substitute x in equation 2:

5(6)-2y=8

30-2y=8

-2y=-22

Therefore y=11
