9x/7-6x = 15 ⟹ 9x=15(7-6x) ⟹ 9x=105-90x ⟹ 9x+90x=105 ⟹ 99x=105 ⟹ x=105/99 ⟹ x=35/33 Class 8 Maths Chapter 2 Exercise 2.6 Solution in Video for more answers vist to: https://www.tiwariacademy.com/ncert-solutions/class-8/maths/chapter-2/

3(5z-7)-2(9z-11) =4(8z-13)-17 ⟹ 15z-21-18z+22=32z-52-17 ⟹ -3z+1=32z-69 ⟹ -3z-32z=-69-1 ⟹ -35z=-70 ⟹ z=-70/-35=2 To check: 3(5z-7)-2(9z-11)=4(8z-13)-17 ⟹ 3(5X2-7)-2(9X2-11)=4(8X2-13)-17 ⟹ 3(10-7)-2(18-11)=4(16-13)-17 ⟹ 3x3-2x7=4x3-17 ⟹ 9-14=12-17 ⟹-5=-5 ⟹ L.H.S. = R. H. S. Therefore, it is correct. CRead more

3(t-3) =5(2t+1) ⟹ 3t-9=10t+5 ⟹ 3t-10t=5+9 ⟹-7t=14 ⟹ t=14/-7 ⟹ t=-2 To check: 3(t-3) =5(2t+1) ⟹ 3(-2-3)=5{2X(-2)+1} ⟹ 3X-5=5(-4+1) ⟹ -15=5X(-3) ⟹ -15=-15 ⟹ L.H.S. = R. H. S. Therefore, it is correct.
