Question 23239: Help with equations. Thank you
Solve for the unknown variable.
1. 0.05x=-10(2)
2. 2y-2*3+1=15
3. 8(1+y)-3y=6+y-2y-10y+20
4. (1/2)x+(9/14)=(3/7)
Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
1. Multiply by "2" to get:
x =-40
2. 2y-6+1=15
2y-5 = 15
2y= 20
y = 10
3.8+8y-3y=6-11y+20
5y+8 = -11y+26
16y = 18
y = 9/8
4. Multiply thu by 14 to get:
7x + 9 = 6
7x = -3
x = -3/7
