Answer:
X is -7 and y is - 5
Explanation:
1) 3x - 8y =19
3x =19 +8y
2) 3x + 5y = - 46
3x = - 46 - 5y
Both equations have the value of 3x so 1= 2
19 +8y = - 46 - 5y
Add 5y to both sides
19 + 13y = - 46
Subract 19 from booth sides
13y = - 65
y = - 5
Substitute the value of y into any of the equations
3x - 8y = 19
3x - (-40) = 19
3x + 40 =19
Subract 40 from both sides
3x = - 21
Divide both sides by 3
X = - 7
