Question

4x-3-1=1
2x+x=9
X-5=-2
X-2=-1

Answer 1

4x - 3 - 1 = 1

4x - 4 = 1

4x = 1 + 4

4x = 5

x = 5/4

2x + x = 9

3x = 9

x = 9/3

x = 3

x - 5 = -2

x = -2 + 5

x = 3

x - 2 = -1

x = -1 + 2

x = 1

Answer 2

Explicação passo-a-passo:

4x=1+3+1

x=5/4

2x+x=9

3x=9

x=9/3

x-5=-2

x=-2+5

x=3

x-2=-1

x=-1+2

x=1
