2/3 x + 1 = 27
subtract 1 from each side
2/3 x = 26
multiply by 3/2
3/2 * 2/3 x = 26 * 3/2
x = 39
10% is 7 dollars so 20% is 14 and have of 7 is 3.5 so it's 17.50
Answer:
(-1,9)
Step-by-step explanation:
y = -3x + 6
y = 9
-3x + 6 = 9
-3x = 3
x = -1
y is already given as 9, but you can solve for y by plugging the x value into y = -3x + 6,
-3(-1) + 6 = 9
(-1,9)
30=(10*3*x)/2
*2 *2
60=10*3*x
60=30x
60/30=30x/30
2=x
