Answer:
Step-by-step explanation:
Lets solve the fraction first
9.6230 x 0.44 = 4.23
4.23 x 3.721 = 15.76
Answer:
15
Step-by-step explanation:
the question has a slope of 1/3x with a y intercept of 2,
Thus, once the line reaches 9 in its y value, the x value would be 15

Step-by-step explanation:
<u>Step 1: Define System</u>
4x + 2y = -1
3x + 4y = 3
<u>Step 2: Rewrite System</u>
4x + 2y = -1
- [Multiplication Property of Equality] Multiply -2 on both sides: -2(4x + 2y) = 2
- [Distributive Property] Distribute -2 on both sides: -8x - 4y = 2
<u>Step 3: Redefine Systems</u>
-8x - 4y = 2
3x + 4y = 3
<u>Step 4: Solve for </u><em><u>x</u></em>
- Combine equations: -5x = 5
- [Division Property of Equality] Divide -5 on both sides: x = -1
<u>Step 5: Solve for </u><em><u>y</u></em>
- Substitute in <em>x</em> [Original Equation]: 3(-1) + 4y = 3
- Multiply: -3 + 4y = 3
- [Addition Property of Equality] Add 3 on both sides: 4y = 6
- [Division Property of Equality] Divide 4 on both sides: y = 3/2
