Question

Resolva as equações do primeiro grau :A)2x+10=50 B)6x-3=57 C)9x+6=60 D)x-8=17

Answer 1

(A

2x=50-10

2×=40

×=40/2

×=20

(C

9x+6=60

9x=54

x=54/9

x=6

(D

1x - 8 = 17  

1x = 17 + 8  

1x = 25  

1x/1 = 25/1  

x = 25

A (B não sei kk

Answer 2

$\large\boxed{\boxed{\boxed{{Ol\'a\:Maria}}}}}$

$A)\:2x+10=50$

$2x=50-10$

$2x=40$

$x=\frac{40}{2}$

$x=20$

-----------------------------------------

$B)\:6x-3=57$

$6x=57+3$

$6x=60$

$x=\frac{60}{6}$

$x=10$

------------------------------------------

$B)\:9x+6=60$

$9x=60-6$

$9x=54$

$x=\frac{54}{9}$

$x=6$

------------------------------------------

$x-8=17$

$x=17+8$

$x=25$
