# Calculate: (3 x+2) (x-1) = 7-7 x
## Expression: $$( 3 x + 2 ) ( x - 1 ) = 7 - 7 x$$
Use the distributive property to multiply $3x+2$ by $x-1$ and combine like terms.
$$3x^{2}-x-2=7-7x$$
Add $7x$ to both sides.
$$3x^{2}-x-2+7x=7$$
Combine $-x$ and $7x$ to get $6x$.
$$3x^{2}+6x-2=7$$
Add $2$ to both sides.
