Question

4x-2y=16 x+3y=-3

Answer 1

You have to solve it by elimination method???

Answer 2

4x - 2y = 16
x + 3y = - 3 -->(-4)x + 3y = - 3
--------------
4x - 2y = 16
-4x - 12y = 12 (result of multiplying by -4)
--------------add
0 - 14y = 28
-14y = 28
y = 28/-14
y = - 2
now sub -2 in for y in either of the original equations
x + 3y = -3
x + 3(-2) = -3
x - 6 = -3
x = -3 + 6
x = 3
lets check...
4x - 2y = 16
4(3) - 2(-2) = 16
12 + 4 = 16
16 = 16 (correct)
ANSWER : x = 3 and y = -2 or (3,-2)
