Solve 70+47=40x+50-77x

$$70 + 47 = 40 x + 50 - 77 x$$

Solve for x

$$x = -\frac{67}{37} = -1\frac{30}{37} \approx -1.810810811$$

Steps for Solving Linear Equation

Add 70 and 47 to get 117.

$$117=40x+50-77x$$

Combine 40x and -77x to get -37x.

$$117=-37x+50$$

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

$$-37x+50=117$$

Subtract 50 from both sides.

$$-37x=117-50$$

Subtract 50 from 117 to get 67.

$$-37x=67$$

Divide both sides by -37.

$$x=\frac{67}{-37}$$

Fraction \frac{67}{-37} can be rewritten as -\frac{67}{37} by extracting the negative sign.

$$x=-\frac{67}{37}$$
