  ​

Choose the correct equation for the given word problem: 3 small cans and 5 large cans have a total of 85 litres of water.

• 3x = 85 + 5y

• x³ + y⁵ = 85

• 3x − 5y = 85

• 3x + 5y = 85

Solve the system by substitution:
y = x + 5
4x + y = 20

• (3,8)

• (8,3)

• (0,2)

• (2,0)

Solve:

3x + y = 3

2x - y = 7

Solve for (x,y)

-2x + 6y = 16

-4x - 3y = 2

• (2,2)

• (-2, -2)

• (-2,2)

• (2,1)

Solve for (x,y)

5x + y = 9

10x − 7y = −18

• (-4,-1)

• (-1,-4)

• (4,1)

• (1, 4)

Solve the system of equations using substitution:

-4x + 4y = 8

y = -2x - 10

• (-4, -2)

• (12, -34)

• (4, -18)

• (-2, -6)

Solve:
x = -3y - 17
2x + 3y = -7

• (1, -20)

• (3, 0)

• (-5, -2)

• (10 , -9)

Solve for x and y.
y = 2/3x - 2
y = -x + 3

• (0,3)

• (0,-3)

• (3,0)

• (-3,0)

Solve for x and y
y = 2x + 1
y = 4x - 1

• (1,3)

• (-1,-3)

• (-1,3)

• (3,1)
