Answer:
15/8 hours .................
Step-by-step explanation:
Let L be Laura, and B be Ben. Then:
3L=1
5B=1
Next:
15L=5
15B=3
15(L+B)=5+3=8
15/8 (L+B)=1
B bc the coefficient is greater than 1. if, for example it was 0.5 it would be a
Answer:
(2,-1)
Step-by-step explanation:
The ys in both questions are isolated on one side of the equation in both. The numerical coefficient of both is 1. Therefore you should equate the the left side of each equation to the other left side. The solution is the easiest one to solve because there is only 1 unknown on both sides.
4x - 9 = x - 3 Subtract x from both sides.
4x-x - 9 = -3 Combine
3x -9 = - 3 Add 9 to both sides
3x - 9+9 = - 3+9
3x = 6 Divide by 3
3x/3 = 6/3
x = 2
===============
Now use the second equation to solve for y
y = x - 3
y = 2 - 3
y = -1
==============
The solution is (2,-1)
