Question

c) 4(2x-1)=-2(x-3)
d) 9(x+1)--28=7

Answer 1

4(2x-1)=-2(x-3)
8x-4=-2x+6
8x+2x=6+4
10x=10
10/10=x
x=1

9(x+1)--28=7
9x+9-28=7
9x=7+28-9
9x=26
x=26/9
x=2,8   Essa letra c deve ta faltando manda de novo.

Answer 2

$c ) 4 ( 2x - 1 ) = - 2 ( x - 3 ) \\ 8x - 4 = - 2x + 6 \\ 8x + 2x = 6 + 4 \\ 10x = 10 \\ x = \frac{10}{10} \\ x = 1 \\ \\ d ) 9 ( x + 1 ) - 28 = 7 ( x - 3 ) \\ 9x + 9 - 28 = 7x - 21 \\ 9x - 7x = - 21 - 9 + 28 \\ 2x = - 2 \\ x = - \frac{2}{2} \\ x = - 1$
