Question

slove the following equations and check your answer: (¡) 3x = 2x + 18 (¡¡) 4z+3= 6+2z (¡¡¡) x=4/5(x+10) (¡V) 3m=5m - 8/5​

Answer 1

Step-by-step explanation:

3x=2x+18

3x-2x=+18

1x=+18

x=18/1

=18

Answer 2

Answer:

(i) 3x-2x=18

therefore, x=18

(ii) 4z+3=6+2z

4z-2z=6-3

2z=3

therefore, z=3/2

(iii) x=4/5(x+10)

x=(4x+40)/5

5x=4x+40

5x-4x=40

therefore, x=40

(iv) 3m=5m-8/5

3m-5m=-8/5

multiple both sides by -1,

5m-3m=8/5

2m=8/5

therefore, m=4/5
