Solve 8-7*(3*x+4)=7+8*x

$$8 - 7 \cdot ( 3 \cdot x + 4 ) = 7 + 8 \cdot x$$

Solve for x

$$x=-\frac{27}{29}\approx -0.931034483$$

Steps for Solving Linear Equation

Use the distributive property to multiply -7 by 3x+4.

$$8-21x-28=7+8x$$

Subtract 28 from 8 to get -20.

$$-20-21x=7+8x$$

Subtract 8x from both sides.

$$-20-21x-8x=7$$

Combine -21x and -8x to get -29x.

$$-20-29x=7$$

Add 20 to both sides.

$$-29x=7+20$$

Add 7 and 20 to get 27.

$$-29x=27$$

Divide both sides by -29.

$$x=\frac{27}{-29}$$

Fraction \frac{27}{-29} can be rewritten as -\frac{27}{29} by extracting the negative sign.

$$x=-\frac{27}{29}$$
