X = 17% of 350
17% = 17/100 = .17
Saying "of" in mathematics is like saying "multiplied by"
x = .17 * 350
x = 59.5

- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define</u>
y = x - 15
y = 4x
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: 4x = x - 15
- [Subtraction Property of Equality] Subtract <em>x</em> on both sides: 3x = -15
- [Division Property of Equality] Divide 3 on both sides: x = -5
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation: y = 4x
- Substitute in <em>x</em>: y = 4(-5)
- Multiply: y = -20
