Answer 1

Step-by-step explanation:

a) 7x - (4x-3) = 2x -5

➻ 7x -(4x -3) = 2x-5

➻ 7x -4x + 3 = 2x-5

➻ 3x + 3 = 2x -5

➻ 3x -2x = -5 - 3

➻ x = -8

• Hence, the value of x = -8.

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

(b) 2/3x + 5 = 1/5 -2x

➻ 2/3x + 5 = 1/5 - 2x

➻ 2/3x + 2x = 1/5 - 5

➻ 2+6/3x = 1-25/5

➻ 8/3x = -24/5

by cross multiplication

➻ 8x × 5 = -24 × 3

➻ 40x = -72

➻ x = -72/40

➻ x = -18/10

➻ x = -1.8

• Hence, the Value of x is -1.8 .
