EOY - Part 2

7(1 - y) = -3(y - 2)

• y = 1/4

• y = 4

• y = 5

• y = -4

Solve the equation for x:

2(3x+7) = x +10 +5x + 4

• x = 2

• x = -4

• no solution

• infinitely many solutions

3x - 8 = 3(x - 4) + 1

Solve the equation. Tell whether the equation has one, no, or infinite solutions.

• one, x = 5

• no solutions

• infinitely many solutions

• one, x = -2

Solve the equation for v:

8v - 4(v + 8) = 8

• v = 2

• v = 10

• v = 4

• v = -4

Solve using Elimination Method:

x - y = 11

2x + y = 19

• (10,-1)

• (-1,10)

• (3,-4)

• (6,7)
