Solve 877=(x*56)+(x*87)+(81-2x*88)

$$877 = ( x \times 56 ) + ( x \times 87 ) + ( 81 - 2 x \times 88 )$$

Solve for x

$$x = -\frac{796}{33} = -24\frac{4}{33} \approx -24.121212121$$

Steps for Solving Linear Equation

Combine x\times 56 and x\times 87 to get 143x.

$$877=143x+81-2x\times 88$$

Multiply 2 and 88 to get 176.

$$877=143x+81-176x$$

Combine 143x and -176x to get -33x.

$$877=-33x+81$$

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

$$-33x+81=877$$

Subtract 81 from both sides.

$$-33x=877-81$$

Subtract 81 from 877 to get 796.

$$-33x=796$$

Divide both sides by -33.

$$x=\frac{796}{-33}$$

Fraction \frac{796}{-33} can be rewritten as -\frac{796}{33} by extracting the negative sign.

$$x=-\frac{796}{33}$$
