Solving systems of equations using substitution/elimination Step-by-step explanation:
<u>Step 1: Define Systems</u>
4x + y = 2
y = x - 3
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
Substitute in <em>y</em>: 4x + (x - 3) = 2 Combine like terms: 5x - 3 = 2 Isolate <em>x</em> term: 5x = 5 Isolate <em>x</em>: x = 1
<u>Step 3: Solve for </u><em><u>y</u></em>
Define equation: y = x - 3 Substitute in <em>x</em>: y = 1 - 3 Subtract: y = -2
