Worksheet on Linear Equations | Linear Equations in One Variable |Free

Practice worksheet on linear equations in one variable. Students can recall the lesson and practice the equations step-by-step and then try to represent the solution of the linear equation graphically.

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

3. Solve the following equations and check your answer:

(i) m – 7 = 1

(ii) y + 7 = 5

(ⅲ) \(\frac{x}{7}\) + 3 = 5

(iv) 2x + 22 = 48

(v) 11k – 5 = 50

(vi) 2p – 10 = – 14

4. For what value of a will the following statements be true?:

(i) 7x + 5 = 26

(ii) 2m – 4 = 18

(iii) z – 9 = – 9

(iv) d – 100 = – 126

(v) k + 8 = 15

(vi) h – 2 = 13

5. Solve the following equations:

(i) p + 8.6 = 26

(ii) z – 2\(\frac{3}{4}\) = 6\(\frac{1}{4}\)

6. Frame the equations and solve them:

(i) If one-fifth of a number is increased by 6, the sum will be 25.

(ii) If y is multiplied by 12, the result is 108.

7. Find the length of a rectangle as shown in the adjoining figure, if its perimeter is 250 metres and breadth is 35 metres.
