If 2z + (8/3) = (1/4) z + 5, then z =?(a)3 (b)3 (c)(2/5) (d)(4/3)

Answer»

(d)(4/3)

Because,

Transposing (8/3) to RHS and it becomes – (8/3) and (1/4)z to LHS it becomes –(1/4)z

= 2z – (1/4)z = 5 – (8/3)

= [(8-1)/4]z = (15-8)/3

= (7/4)z = 7/3

Multiplying both side by (4/7).

= (7/4)z × (4/7) = ((7/3) × (4/7)

= x = 4/3
