Question 1076557

Solve each pair of equation given below using elimination method:X+2y=-4.     3x-5y=-1
<pre>I'm assuming that X is same as x. Do not write X and x as they signify 2 DIFFERENT variables
x + 2y = - 4 ------- eq (i)
3x - 5y = - 1 ------ eq (ii)
- 3x - 6y = 12 ----- Multiplying eq (i) by - 3 ------ eq (iii)
   - 11y = 11 ------ Adding eqs (iii) & (ii)
{{{highlight_green(matrix(1,5, y, "=", 11/(- 11), "=", - 1))}}}
Substitute - 1 for y into any of the 2 original equations to get the value of x.
