Question

A) -3(-2×+2)=5+2(-2+×). B) -5(×+4)=4(-2+×)
Me ajuda!!!!​

Answer 1

a) $-3(-2x + 2 ) = 5 + 2(-2 + x)$

$6x - 6 = 5 - 4 + 2x$

$6x - 6 = 1 + 2x$

$6x - 2x = 1 + 6$

$4x = 7$

$x = \frac{7}{4}=1,75$

b) $-5(x+4) = 4(-2+x)$

$-5x - 20 = -8 + 4x$

$-5x - 4x =-8 + 20$

$-9x = 12 (.-1)$

$9x = -12$

$x = -\frac{12}{9}$

$x=-\frac{4}{3}=-1,3$
