Chapter 6: Linear Equations (F1)

State the linear equation in one variable that suitable for this situation:

"The price of chicken is RMb per kilogram. Rozita bought 3 kg of chicken and made a total payment of RM21."

• 3 $+$ b = 21

• 3 $-$ b = 21

• 3 $\times$ b = 21

• 3 $\div$ b = 21

Find the value of x.

3x + 3 = 15

Find the value of y.

 $\frac{2}{3}$ y – 9 = 7

Find the value of m.

2(m + 4) = 22

Find the value of k.

4k – 8 = 10k + 16

Which of the following equations are linear equations in one variable?

• $y^2+3y=1$

• $3j+2=5$

• $2(k–7)=k$

• $p–4q=6$

Write a linear equation based on the image given.

Which of the following equations are linear equations in two variables?

• $\frac{y}{6}+4=–2x$

• $5a^3–4=4b$

• $3h–1=5k$

• $k+1=6$

Form a linear equation in two variables for the following situation:

"The sum of two numbers is 186."

• $j+k=186$

• $j-+k=186$

• $j\times k=186$

• $j\div k=186$

Form a linear equation in two variables for the following situation:

"The different between the price for 6 plates of nasi lemak and 3 plates of fried noodles is RM39."

•  $39-6x=3y$  

•  $6x=39\ -3y$  

•  $6x+3y=39$  

•  $6x-3y=39$
