Solving equations with variable on both sides Part 1

-9 +2X = 5X X -9 = 3X = 3X 33 X = -7

-5 – X = 4X X -5 = 5X = 5X 55 X = 2

12X + 3 = 4X X 12X + 3 = 3X X 9X + 3 = X = X = 2.6 1

0 + 3X = 5X X 0 = 2X = 2X 22 X = 5

Pg – 16 even

8 – (2 – 2X) = -4X + 3(4X + 5) X = -4X + 12X X = 8X X 6 = 6X = 6X 66 X = - 1.5

2 – 15n = 5(-3n + 2) 2 – 15n = -15n n 2 = 10 2 can’t equal 10 so this equation has no solution

5(1 + 4m) = 2( m) m = m -20m 5 = 5 5 will always equal 5 so this equation has all solutions
