The number is 18 . A ) The equation is 12 + 10 x = 192 B ) x = 18 .
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 (i.e. only one variable), then it is known as a linear equation in one variable. A linear equation can have more than one variable.
B ) Solving above equation 12 + 10 x = 192
10 x = 192 -12
10 x = 180
