Question 468432
I need to use any method to solve:
{{{x/2-y/4}}} = -4
x + y = -2
:
Multiply the 1st equation by 4, resulting in
2x - y = -16
 x + y = -2
----------------adding eliminates y, find x
3x = -18
x = {{{(-18)/3}}}
x = -6
Find y
x + y = -2
-6 + y = -2
y = -2 + 6
y = 4
:
:
Check solutions, in the 1st original equation
{{{x/2-y/4}}} = -4
{{{(-6)/2-4/4}}} = -4
{{{(-6)/2}}} - 1 = -4
-3 - 1 = -4
