Form 1 Math Chapter 6

Choose the statement that corresponds to 2x+7=10.

• Twice a number added to 7 gives 10

• Juan buys two chickens and has 10 chickens after adding 7

Which of the following is a linear equation in one variable?

Solve 6(2x+3)=10x

• x= 18

• x = 9

• x = -9

• x = -18

• x= 5

• x= 25

• x= 51

Cikgu Jamal has made an order online. He orders 25 medals for the 100 m event and 15 medals for the 200 m event as prizes in the school's annual sports event. The amount spent by Cikgu Jamal to buy the prizes is RM350.

• 100m + 200m = RM350

• 100x + 200y = RM350

• x+y=RM350

• 25x+15y=RM350

Which of the following is a pair of simultaneous linear equations in two variables?

• x+y=3, z+k=5

• r+s=10, 2s-3r=15

• z+k=7, w+q=3

• 3s+y=10, 3w+q=6

Find the values of x and y for the following simultaneous linear equations.

x+2y=14

2x+3y=7

• x = 28, y =-21

• x =14, y =28

• x = -28, y = 21

• x =28, y =-14

The product of a number multiplied by 7 is 28.

• 7xy = 28

• 7y = 28

• y = 28

• x =28

Azlma is 10 years younger than her 30-year-old sister.

Form a linear equation.
