One number is x
other number is 3x-10
x + 3x - 10 = 50
4x = 50 + 10
4x = 60
x = 60/4
x = 15 ← one number
the other number = 3x - 10 = 3*15 - 10 = 35
The x-coordinate of the solution. 1
So a-47=b
so total value =113 times 1,000,000=113,000,000=a+b
subtitute a-47=b into equation
a+a-47=113,000,000
add 47 to both sides
2a=113,000,047
divide both sides by 2
$56,500,023.5=a or <u>roughly</u> 56.5 million
a-47=b
56,500,032.5-47=b
56,499,976.5=b
so 56,500,023.5=a
56,499,976.5=b
When you multiplied both sides by a NEGATIVE number, what WAS negative became positive, and what WAS positive became negative! Everything that was larger became small, and what was smaller became large. Everything REVERSED
The 32 and 64 aren't even
