Is this right? 7(3x-2)=70
21x-14=70; 21x-14+14=70+14; 21x=84; x=4
correct
So is this even right? I was born that year, math has changed since then.
Yes, your solution is correct. Let me break down the steps for solving the equation:
1. Start with the equation: 7(3x-2) = 70.
2. Distribute the 7 on the left side of the equation: 21x - 14 = 70.
3. Add 14 to both sides of the equation to isolate the term with 'x': 21x - 14 + 14 = 70 + 14.
4. Simplify and combine like terms: 21x = 84.
5. Divide both sides of the equation by 21 to solve for 'x': x = 4.
Therefore, the value of 'x' that satisfies the equation is 4.
