Question

6(-2x+5)=-18 

2(4x+1)-3(2x+3)=5 

 

não sei essas equações espero que me ajude !!

Answer 1

6(-2x+5)=-18
-12x+30=-18
-12x=-18-30
x=-48/-12
x=4

2(4x+1)-3(2x+3)=5
8x+2-6x+9=5
8x-6x=5-2-9
2x=-6
x=-6/2
x=-3

Answer 2

$\[\\6(-2x+5)=-18 \\-12x+30=-18 \\-12x=-18-30 \\-12=-48(-1) \\12x=48 \\\\x=\frac{48}{12} \\\\\boxed{x=4}\]$

$\[\\2(4x+1)-3(2x+3)=5 \\8x+2-6x-9=5 \\2x=5-2+9 \\2x=3+9 \\2x=12 \\x=\frac{12}{2} \\\boxed{x=6}\]$
