Answer:
It is -0.48
Step-by-step explanation:
Y = 2x - 2
x + 3y = 15
I'll do substitution by solving for y:
y = 2x - 2
Solve for y for the second equation:
y = 5 - x/3
Substitute:
2x - 2 = 5 - x/3
Add x/3 to both sides:
7x/3 - 2 = 5
Add 2:
7x/3 = 7
Multiply by 3:
7x = 21
Divide by 7:
x = 3
Substitute x in for one of the original equations:
y = 2(3) - 2
y = 6 - 2
y = 4
The solution set is (3, 4).
Answer: 186+14-26+5=179 pounds
Step-by-step explanation:
1. Regainged 5 pounds and weighed 179 pounds = So he weiged 179-5=174 pounds."and lost 26 pounds"
2. To weigh 174 pounds,so he used to weigh 174+26=200 pounds, David gained 14 pounds over the winter, so he weighed 200-14=186 pounds.
3. Check 186+14-26+5=179 pounds
If you are doing algebra, then X+14-26+5=179
Solve for X.
