Question

Linear equations in one variable class 7 worksheet

Answer 1

1. Solve each of the following equations and represent the solution graphically.

  (a) 7x + 2 = -19

  (b) 3x - 1/3 = 5 

  (c) 5x - 4 = 21

  (d) -7x = 21 

  (e) 18 - 7x = -3 

  (f) 3(x + 4) = 21 

  (g) 2x/3 - 3x/5 = 8 

  (h) 3x - 9 = 5x - 3 

  (i) 3(x - 3) = 4(2x + 1) 

2. Solve each of the following equations and check your solution by substituting in the equation. 

  (a) 3x/2 - 10 = 1/2 

  (b) x/2 - x/3 = 8 

  (c) 6x - 9 - 2(1 - x) = x + 9

  (d) 2(x - 2) - 5(x - 5) = 4(x - 8) - 2(x - 2) 

  (e) (2 - y)/(y + 7) = 3/5 

  (f) (3x + 2)/(2x - 3) = - 3/2 

  (g) (x - 8 )/3 = (x - 3)/5 

  (h) 0.25(4y - 3) = 0.5y - 9
