Question

Someone Please Help!
Solve a system of linear equations using substitution, elimination OR substitution!
3x - y = -137
y = 2x + 99

Answer 1

3x - y = -137
y = 2x + 99


3x - y = -137 plug in y from the 2nd equation
3x - (2x + 99) = -137
3x - 2x - 99 = -137
x - 99 = -137
x = -137 + 99
x = -38

y = 2x + 99
y = 2(-38) + 99
y = -76 + 99
y = 23

Answer 2

Theres also,
2.) -x + 2y = -2
x + 4y = -10
3.) 2x + y = -1
3x - y = 16
I have to solve one for each system of linear equations!:(
