I need help with Systems of equations

Question

R₁T₁₌ R₂T_{2 ,} T₁₊ T₂₌ 60, R₁₌3, R₂₌6  Please help me find the value of T_{1 and} 

 T₂

Answer 1

R1T1= R2T2 , T1+ T2= 60, R1=3, R2=6

 

 

R1T1= R2T2

3T1 = 6T2 ----------------substitute the value of R1, R2

 

T1 + T2 =60

T1 =60-T2

 

Substitute this value of T1 in 3T1 = 6T2 

3T1 = 6T2

3(60-T2) =6T2

 

90 -3T2 =6T2

90 =9T2

 

10 =T2

 

T1+T2 =60

T1 + 10 =60

T1 =50

 

T1 =50 and T2 =10
