Multiply the first equation by 2:-
2y + 4.6 = 0.90x
2y - 0.90x = -4.6
second equation is
-2y - 4.2x = -7.8
Adding:-
-5.1x = -12.4
x = 2.4
-2y = -7.8 + 4.2(2.4) = 2.3
x = -1.2
Answer x = 2.4 and y = -1.2
Its choice A
Step-by-step explanation:
ANOVA table Source SS df MS F
p-value Factor 1 12.00 1 12.000 1.20 .3153
Factor 2 8.00 2 4.000 0.40 .6870 Interaction 56.00 2 28.000 2.80 .1384
Error 60.00 6 10.000 Total 136.00 11
Since the p -value for Factor A is greater than 0.1, therefore Factor A is not significant. The p -value for Factor B is greater than 0.1, therefore Factor B is not significant. It should be noted that for P-value of both Factor and Factor B to be significant, each factor must not be greater than 0.1
