- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
-3(x - 1) = x - 5
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute -3: -3x + 3 = x - 5
- Add 3x to both sides: 3 = 4x - 5
- Add 5 to both sides: 8 = 4x
- Divide 4 on both sides: 2 = x
- Rewrite: x = 2
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: -3(2 - 1) = 2 - 5
- Subtract: -3(1) = -3
- Multiply: -3 = -3
Here we see that -3 does indeed equal -3.
∴ x = 2 is a solution of the equation.
Answer:
slope = 
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
3(y - 1) = 2x + 2 ← distribute parenthesis on left side
3y - 3 = 2x + 2 ( add 3 to both sides )
3y = 2x + 5 ( divide all terms by 3 )
y =
x +
← in slope- intercept form
with slope m =
