Practice: Simultaneous Linear Equations

 $3\left(x+1\right)=5\left(x-1\right)$  

Find the value of x.

Tick for the linear equations in two variables.

• $\frac{p}{4}+16=q$

• $20-h\ =\ 4h$

• $3r+23=11s$

• $x^2+y=3$

• $16g+h=9$

Solve the simultaneous linear equation.

 $2m-5n\ =\ -1$  

 $m+n=10$  

•  $m=3,\ n=7$  

•  $m=7,n=3$  

•  $m=7,\ n=-3$  

 $\frac{9m-3}{4}=6+3m$  

Find the value of m.

 $2x+3y=4$ 
  $x-4y=-9$  

The above information shows the linear equations to be solved simultaneously. By eliminating x, which of the following can we get? 

•  $5y=22$  

•  $11y=22$  

•  $-5y=22$  

•  $-11y=22$  

A shop is having a promotion sale on orange juice and biscuit. Based on the picture above, write a linear equation assuming orange juice is p and biscuit is q.

Puan Rohaya spent RM58 to buy 5 kg of honeydew and 7 kg for starfruit. Encik Ramli buys 1 kg of honeydew and 4 kg of starfruit for price RM22.

Find the price for 1 kg of honeydew and 1 kg of starfruit.

• Starfruit = RM3, Honeydew = RM4

• Starfruit = RM4, Honeydew = RM6
