Question

Encuentren el valor de x en cada caso

4x+3=2x+5
3x+1=x+5
x+10=5x+2

Answer 1

4x+3=2x+5
4x-2x = 5-3
2x = 2
x = 2/2
x =1

3x+1=x+5
3x-x = 5-1
2x = 4
x =4/2
x =2

x+10=5x+2
10-2 = 5x-x
8 = 4x
8/4 = x
2 = x

Answer 2

4x+3=2x+5
4x-2x=5-3
2x=2
$\frac{2x}{2} = \frac{2}{2}$
x=1

3x+1=x+5
3x-x=5-1
2x=4
$\frac{2x}{2} = \frac{4}{2}$
x=2

x+10=5x+2
x-5x=2-10
-4x= -8
$\frac{-4x}{-4} = \frac{-8}{-4}$
x=2
