Question

$$3 ( x - 4 ) + 5 = 3 x - 7$$

Solve for x (complex solution)

$x\in \mathrm{C}$

Solution Steps

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

$$3x-12+5=3x-7$$

Add $-12$ and $5$ to get $-7$.

$$3x-7=3x-7$$

Subtract $3x$ from both sides.

$$3x-7-3x=-7$$

Combine $3x$ and $-3x$ to get $0$.

$$-7=-7$$

Compare $-7$ and $-7$.

$$\text{true}$$

This is true for any $x$.

$$x\in \mathrm{C}$$

Solve for x

$x\in \mathrm{R}$

Solution Steps

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

$$3x-12+5=3x-7$$

Add $-12$ and $5$ to get $-7$.

$$3x-7=3x-7$$

Subtract $3x$ from both sides.

$$3x-7-3x=-7$$

Combine $3x$ and $-3x$ to get $0$.

$$-7=-7$$

Compare $-7$ and $-7$.
