Question

Solving linear equation using rule of transposition: [1x3=3]

(1) 3 (5x-2) – 4 (x+ 4)= 7 (x-1) + 1. pls help me​

Answer 1

x = 4.25

Step-by-step explanation:

3(5x - 2) - 4(x + 4) = 7(x - 1) + 1

= 15x - 6 - 4x + 16 = 7x - 7

= - 6 + 16 + 7 = 7x + 4x - 15x

= 1 + 16 = - 8x + 4x

= 17 = - 4x

= 17 / 4 = x

= 4.25 = x
