Respuesta :
-4×(1.75+x)=-4×1.75+-4×x=7-4x
-7-4x=18
18-(-7)=18+7=25
-4x=25
25÷(-4)=-6.25
x=-6.25
-7-4x=18
18-(-7)=18+7=25
-4x=25
25÷(-4)=-6.25
x=-6.25
The required solution is [tex]x=\frac{-25}{7}[/tex]
Given equation is,
[tex]-4(1.75+x)=18[/tex]
Simple linear equation:
Linear equations are equations of the first order. The linear equations are defined for lines in the coordinate system. When the equation has a homogeneous variable of degree 1.
Now, solving the given equation,
[tex]-4(1.75+x)=18\\-7-4x=18\\-4x=18+7\\-4x=25\\x=\frac{-25}{7}[/tex]
