Solve for x and y: 3x + 2y = 16 and 5x - y = 9

• x = 3, y = 2

• x = 4, y = 2

• x = 3, y = 4

• x = 2, y = 5

Simplify: (4/5) ÷ (2/3)

• 6/5

• 8/15

• 10/7

• 12/15

Rearrange for y: 2x + 3y = 12

• y = (12 - 2x) / 3

• y = 12 + 2x / 3

• y = (3x - 12) / 2

• y = (12 + 2x) / 3

Solve for x: 2x/3 = 5/6

• x = 5/4

• x = 5/9

• x = 5/3

• x = 5/2

Solve simultaneously: x + y = 7, 2x - y = 1

• x = 3, y = 4

• x = 2, y = 5

• x = 4, y = 3

• x = 5, y = 2

Simplify: (7/8) × (4/5)

• 28/40

• 7/10

• 7/12

• 28/35

Rearrange for x: ax + bx = c

• x = c / (a + b)

• x = (a + b) / c

• x = c - (a + b)

• x = c / (ab)

Solve for x: 3(x + 2) = 2(x - 1)

• x = -8

• x = -4

• x = 4

Simplify: (5/6) ÷ (10/12)

• 1

• 1/2

• 5/6

• 5/4

Solve for y: 4x - 5y = 20 and x + y = 5

• x = 7, y = -2

• x = 10, y = -5

• x = 5, y = 0

• x = 2, y = 3
