Answer:
240%
Step-by-step explanation:
221 - 65 / 65 = x
156 / 65 = x
x = 2.4
2.4 = 240%
Lets try substitution5x+2y=21=5x=21-2y=x=(21-2y)/5
sub into second equation
-2(21-2y)/5+6y=-34(-42+4y)/5+6y=-34solve for yy=-64/17plug into equation and solve for x=(97/17)
The correct answer is: [A]: " x = 3 " .
