5x+4y=-2
3x+4y=10
Make one with negative coefficient to find first what is x then solve for y .
-1(5x+4y)= -1 (-2)
3x+4y=10
-5x-4y=2
+ 3x+4y=10
_________
-x = 12
Divide both sides by -2
-2x/-2=12/-2
X= -6
Now substitute your x into one of the equations to find y .
-5x-4y=2
-5(-6)+4y=2
30+4y=2
Subtract 30 both sides
-4y= 2-30
Divide both sides by -4
Y= -28/-4
Y= 7
Your answer is in point form (-6,7) meaning x is -6 and y is 7.
Answer:
30 inches
Step-by-step explanation:
She takes 12 equal sized steps and they all add up to 10 yards.
The length of each step (in yards) is:
10 / 12 = 5/6 yards
The question requires the answer in inches, therefore, we must convert this to inches:
1 yard = 36 inches
5/6 yards = 5/6 * 36 = 30 inches
Each step is 30 inches long.
