5r + 6s = 53
25r + 3s = 49
Meaning of simultaneous is to solve by elimination
Multiply the equation 2 by -2
-2( 25r + 3s = 49)
-50r – 6s = -98
Then add the two equation to eliminate s, so the resulting equation is:
-45r =-45
r = 1
substitute r = 1 to equation 1
5(1) + 6s = 53
6s = 53 – 5
6s = 48
<span>S = 8</span>
The third term would be 5h2 because the descending order would be
-2h4 - 8h3 + 5h2 - 2h - 3
Y = 2x + 5 that is my answer
Sixty-seven times a number, plus eight and nine tenths, is not greater than negative three hundred two
It the answer
