Matched Exercise 1 Simplify the expression
2(a - 8b) - (5 - b) + b + (6b - 9) - a
Solution to Exercise 1
a - 8b -14
Matched Exercise 2: Solve the equation
2(-x - 5) - (-6 + x) = -3(2x + 4) + 12
Solution to Exercise 2
x = 4/3
Matched Exercise 3: If x
> 3, simplify the expression
2| x - 3 | + 6x - (2 - 3x) + | 9 - 20 |
Solution to Exercise 3
11x + 3
Matched Exercise 4: Find
the slope and the y-intercept of the line given by the equation
-3y - 6x = 7
Solution to Exercise 4
slope = -2
y intercept at (0 , -7/3)
Matched Exercise 5: Find
the equation of the line passing through the points (0 , 3) and (-1 ,
1).
Solution to Exercise 5
y = 2x + 3
