Solving systems of equations using substitution/elimination Step-by-step explanation:
<u>Step 1: Define systems</u>
x - 4y = 12
x - 5y = 15
<u>Step 2: Solve for </u><em><u>y</u></em>
<em>Elimination</em>
Subtract 2 equations: y = -3
<u>Step 3: Solve for </u><em><u>x</u></em>
Define original equation: x - 4y = 12 Substitute in <em>y</em>: x - 4(-3) = 12 Multiply: x + 12 = 12 Subtract 12 on both sides: x = 0

It’s 6 because if you divide 12 divided by 2 that’s 6 and to check it multiply 6x2=12
Answer:
0.75 about that in each sequence
If your denominators are x² + 4x - 12 = (x +6)(x -2) and x² + 7x + 6 = (x +6)(x +1) Then the common denominator is the product of unique factors: (x +6)(x +1)(x -2)
1 gallon = 3.78541 liters.
Multiply the number of gallons by 3.78541:
10 x 3.78541 = 37.8541 liters (round the answer as needed)
