- Terms/Coefficients
- Coordinates (x, y)
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
y = 2x - 1
2x + 4y = 26
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: 2x + 4(2x - 1) = 26
- Distribute 4: 2x + 8x - 4 = 26
- Combine like terms: 10x - 4 = 26
- [Addition Property of Equality] Add 4 on both sides: 10x = 30
- [Division Property of Equality] Divide 10 on both sides: x = 3
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define equation: y = 2x - 1
- Substitute in <em>x</em>: y = 2(3) - 1
- Multiply: y = 6 - 1
- Subtract: y = 5

We can do the elimination method to find the solution for this problem. The elimination method involves adding the two equations together to get rid of a like term.
x + 2y = 7
+ x - 2y = -1
—————————
2x = 6
Now that we eliminated 2y because they cancel out, we are left with 2x = 6. Divide both sides by 2 in order to get x.
The answer is: x = 3.
Now that we know the numerical value of x, all we have to do is plug x into either system of equation in order to find the numerical value of y.
x + 2y = 7
3 + 2y = 7
2y = 4
y = 2
The solution to the problem is (3, 2).
Answer 1) x = 7 so in 7 months
2) 43,425 + 75x = 45,000 - 150x
Step-by-step explanation:
basically town A is gaining 75 people monthly and town B is decreasing 150 monthly so 43,425 + 75x = 45,000 - 150x and then you find out in 7 months both town will have equal population hope i helped
