Question

Solve 4(2x-8) = 3(x+6)
Which mathematical sign will replace ✸ mark if
x = 3 is a solution of the equation 3x ✸ 2 = 7?

Answer 1

Answer:

4(2x-8) = 3(x+6)

=(8x-32) = (3x+18)

=8x-3x = 32+18

=5x= 50

=x = 10

Step-by-step explanation:

3x - 2 = 7

= 3x = 7+2

= 3x = 9

= x = 3

so, sign = -
