Answer:

.
Step-by-step explanation:
5x + 3y = 26 (times 6) 30x + 18y = 156
6x + 7y = 21 (times 5) 30x + 35y = 105
.
30x + 18y = 156
<u>30x + 35y = 105 </u> <u> </u>
-17y = 51

y = -3
.
Substitute the value of y to one of equations
6x + 7y = 21
6x + 7(-3) = 21
6x - 21 = 21
6x = 21 + 21
6x = 42

x = 7

Step-by-step explanation:
<em>Answer,</em>
100,000,000 > 334,605,925
But, 100,000,000 is smaller that 334,605,952
So, It would be "100,000,000 < 334,605,925"
-31F because of the formula.
-35°C multiplied by 9/5 +32 = -31°F
