Answer:
(-2,9) ,(4,-3)
Step-by-step explanation:
Given the expression 2x+y=5
We are required to look for values of x and y such that when substituted into the given expression will result in the number 5
The Pairs are (-2,9) ,(4,-3)
Let us plug in the values to check
1. (-2,9)
2(-2)+9=5
-4+9=5
5=5 true
2. (4,-3)
2(4)+(-3)=5
8-3=5
5=5 true
Yes, a good tip would either be $3 or $4. To calculate the tip, you just take the overall total and multiply it by the percentage in decimal form.
Total = $22
15% = .15
20% = .20
(22) x (.15) = 3.3 = $3
(22) x (.20) = 4.4 = $4
Answer:
- Equation 3y = -42
- Solved: y = -14
Step-by-step explanation (to solve the equation):
- Divide each side by 3 to cancel out the 3 next to y. It should now look like this: y = -14
