6. SOLVING FOR A VARIABLE
1. The equation is: 7 + 8 = 15. Using the same three
numbers, what does 7 = ? What does 8 = ?
2. x + y = 15; x = ?; y = ?
3. 12 - 7 = 5; x - y = 5; x = ?; y = ?
4. Solve: PQ = X, for Q
5. Solve: 12 - b = 2t, for t
7. Solve: R = C - S, for C
T
6. V = (1/3)AH, for H

TEMPERATURE FORMULA
Most of the world uses the Celsius Scale, while others,
including the US, use the Fahrenheit scale.
The formula to convert from Celsius is F = 9/5C + 32.
The formula to convert from Fahrenheit to Celsius is C =
5/9(F - 32)
Convert from one temperature to the other.
32 °C, 32 °F
8. EQUATIONS:
THERE ARE ONLY 4 OPERATIONS WHICH CAN BE
PERFORMED: +, -, *, /
2|X + 4|+ 6 = 14
OUR GOAL IS TO GET THE X
ALONE ON THE LEFT SIDE
WE DO THIS BY PERFORMING THE OPPOSITE
OPERATION TO REMOVE VALUES ONE AT A TIME FROM
THE LEFT HAND SIDE.
2|X + 4| = 14
REMOVE THE +6 BY PERFORMING THE
. THEN REMOVE THE 2 BY PERFORMING
THE
