Question

Cuanto es2x -10=3x -30

5w+2=10w -3

4y -7=2y+3

Answer 1

¡Hola!

1.
$2x - 10 = 3x - 30 \\ 30 - 10 = 3x - 2x \\ 20 = x$

2.
$5w + 2 = 10w - 3 \\ 2 + 3 = 10w - 5w \\ 5 = 5w \\ \frac{5}{5} = w \\ 1 = w$

3.
$4y - 7 = 2y + 3 \\ 4y - 2y = 3 + 7 \\ 2y = 10 \\ y = \frac{10}{2} \\ y = 5$

Espero que te sirva de ayuda ^^

Answer 2

2x -10=3x -30
-10+30=3x-2x
$\boxed{20 = x}$

5w+2=10w -3
2+3=10w-5w
5=5w
5/5=w
$\boxed{1 = w}$

4y -7=2y+3
4y-2y=3+7
2y=10
y=10/2
$\boxed{y = 5}$
