x = 
subtract 4x from both sides of the equation
6x - 4x - 2 = 13
2x - 2 = 13
add 2 to both sides
2x = 13 + 2 = 15
divide both sides by 2
x =
Answer:
x = 12
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
-2(x - 4) = -16
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute -2: -2x + 8 = -16
- Isolate <em>x</em> term: -2x = -24
- Isolate <em>x</em>: x = 12
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: -2(12 - 4) = -16
- Subtract: -2(8) = -16
- Multiply: -16 = -16
Here we see that -16 does indeed equal -16.
∴ x = 12 is a solution of the equation.
Answer:
A.) 126°
Step-by-step explanation:
180-54=126
A straight line equals 180°
So you can subtract 180° by the known angle to find the unknown angle.
