Answer:

[tex] \times = - 3[/tex]

Step-by-step explanation:

3x+2x-5=8x+4

collect like terms

[tex]5 \times - 5 = 8 \times + 4[/tex]

move the variable to the left hand side and change its sign

[tex]5 \times - 8 \times - 5 = 4 \\ [/tex]

move the constant to the right hand side and change its sign

[tex]5 \times - 8 \times = 4 + 5[/tex]

collect like terms

[tex] - 3 \times = 4 + 5 \\ add \: the \: numbers \\ - 3 \times = 9[/tex]

divide the both sides of the equation by -3

[tex] \times = - 3[/tex]
