1) combine like terms and divide by the x value
Solve. 3(x + 1) - 2x = -6. A) x = 1 B) x = 5 C) x = -7 D) x = -9 6) 3x + 2y = 2 -2x + y = 8 Solve the system of equations. A) (-2,4) B) (4,-2) C) (-4,-2) D) ( 5 4 , - 1 2 ) 7) Solve for x: 4x + 12 = 8 (given) 4x = -4 (subtraction) x = -1 What is the reason for the last step in the argument? A) division B) addition C) subtraction D) symmetric property 8) 2(x + 7) + 3x = 12 (given) 2x + 14 + 3x = 12 (?) 5x + 14 = 12 (simplify) 5x = -2 (subtraction) x = - 2 5 (division) What is the missing reason?

Which one of your questions have you tried working out?
No offense but I will not work these out until you tell me what you think the answer is. I have spent years learning all of the math I have. This isn't a Google service
For all of these problems, you need to isolate your variable by subtraction and then division. That's essentially the formula for most of these. Also, think of items as variables. Then apply my previous advice.
