Solve y-129.81=4.43(x-1)

$$y - 129.81 = 4.43 ( x - 1 )$$

Solve for x

$$x=\frac{100y-12538}{443}$$

Steps for Solving Linear Equation

Use the distributive property to multiply 4.43 by x-1.

$$y-129.81=4.43x-4.43$$

Swap sides so that all variable terms are on the left hand side.

$$4.43x-4.43=y-129.81$$

Add 4.43 to both sides.

$$4.43x=y-129.81+4.43$$

Add -129.81 and 4.43 to get -125.38.

$$4.43x=y-125.38$$

Divide both sides of the equation by 4.43, which is the same as multiplying both sides by the reciprocal of the fraction.

$$\frac{4.43x}{4.43}=\frac{y-125.38}{4.43}$$

Dividing by 4.43 undoes the multiplication by 4.43.

$$x=\frac{y-125.38}{4.43}$$

Divide y-125.38 by 4.43 by multiplying y-125.38 by the reciprocal of 4.43.

$$x=\frac{100y-12538}{443}$$

Solve for y

$$y=\frac{443x}{100}+125.38$$

Solution Steps

Use the distributive property to multiply 4.43 by x-1.

$$y-129.81=4.43x-4.43$$

Add 129.81 to both sides.

$$y=4.43x-4.43+129.81$$

Add -4.43 and 129.81 to get 125.38.

$$y=4.43x+125.38$$
