Answer:

x = 10

Explanation:

4x + 3(x - 1) = 67 ← distribute parenthesis and simplify left side

4x + 3x - 3 = 67

7x - 3 = 67 ( add 3 to both sides )

7x = 70 ( divide both sides by 7 )

x = 10

Hi. . .

A n s w e r : -


\boxed{\fbox{\huge{x = 10}}}

E x p l a n a t i o n :

Let's solve your equation step-by-step ~

➳ Step 1: Simplify both sides of the equation.


\sf{4x \: + \: 3(x \: - \: 1) = 67}


\sf{4x \: + \: (3)(x) \: + \: (3)(-1) = 67} \: (Distribute)


\sf{4x \: + \: 3x \: + \: -3 = 67}


\sf{(4x \: + \: 3x) \: + \: (-3) = 67} \: (Combine \: like \: terms)


\sf{7x \: + \: 7 \: -3 = 67}


\sf{7x \: - \: 3 = 67}

➺ Step 2: Add 3 to both sides.


\sf{7x \: - \: 3 \: + \: 3 = 67 \: + 3}


\sf{7x = 70}

➽ Step 3: Divide both sides by 7.


\sf{(7x)/(7) = (70)/(7)


\boxed{\fbox{\huge{x = 10}}}

Hope It Helps...
