2x+2y=-98

Answer 1

Please show work, i will give you a medal if you answer

Answer 2

solve for y in the first equation:
y = -92 - 2x
then substitute this in for y in the second equation:
2x + 2(-92 - 2x) = -98
expand and simplify:
2x - 184 - 4x = -98
-2x = 86
x = -43
then substitute this in for x in the first equation:
2(-43) + y = -92
y = -92 + 86 = -6
your solution is (-43, -6)
