2x+4y=22, 2x-2y=-8
solving systems using elimination. can you solve and show your work

2x+4y=22
2x-2y=-8
subtract
6y = 30
y = 30/6
y = 5

2x+4y=22
2x+4(5)=22
2x + 20 = 22
2x =22 -20
2x = 2
x = 1

x = 1 and y = 5

Answer: the correct answer is 10step-by-step explanation: let the number be n, then the expression becomes,then“twelve more than the quotient of a number and two, decreased by four” iswhen n=4,we substitute 4 whetever we see n to get,we simplify to obtain,we further simplify to get,therefore the correct answer is c.
