- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
-6x + 5y = 34
-6x - 10y = 4
<u>Step 2: Rewrite Systems</u>
-6x + 5y = 34
- Multiply everything by -1: 6x - 5y = -34
<u>Step 3: Redefine Systems</u>
6x - 5y = -34
-6x - 10y = 4
<u>Step 4: Solve for </u><em><u>y</u></em>
<em>Elimination</em>
- Combine 2 equations: -15y = -30
- Divide -15 on both sides: y = 2
<u>Step 5: Solve for </u><em><u>x</u></em>
- Define equation: -6x - 10y = 4
- Substitute in <em>y</em>: -6x - 10(2) = 4
- Multiply: -6x - 20 = 4
- Add 20 on both sides: -6x = 24
- Divide -6 on both sides: x = -4
Answer:
The value of x = 43/9 or x = 4.78
Step-by-step explanation:
Given the equation
<u />
<u>Solving for x</u>
Subtract 6 from both sides
Simplify
Divide both sides by 18
Simplify
or
Therefore, the value of x = 43/9 or x = 4.78
