Subtract 3 first so it would be 7x=15
then divide by 7 so x would be approximately 2.14
Answer:
X = 51
Y = 12
Step-by-step explanation:
2 numbers: (Larger) Number 1 is x and Number 2 is y
The equation is x + y = 63
New equation is:
Combine like variables:
Solve:
- 4y + 15 - 15 = 63 - 15
- 4y = 48
Divide 4 from each side:
To find x fill in the variables from the 'x =' equation:
- x = 3y + 15
- x = 3( 12) + 15
- <em><u>x = 51</u></em>
From 55 mph to 70 mph is a 36% increase.
I hope this helped!
You divide 12/29 and that gives you 0.4137 which equals 41 percent
3(d+2)-12 = d-2
3d +6 -12 = d - 2
3d-d = 12 - 6 - 2
2d = 4
d = 2
