7x-15=33 solve the equation and you should ger x= 2.57
Answer: y= -1/5x + 3
15y= -3x + 45
y= -3/15x + 3
y= -1/5x + 3
I have attached my work and the rules of exponents
Answer:
the coefficient of x is 2
Step-by-step explanation:
(3x - y + z) + (2x - y - z) - (3x - y - z) = 3x - y + z + 2x - y - z - (3x - y - z)
Apply the distributive law: - (a - b) = -a + b
Therefore, - (3x - y - z) = -3x + y + z
So (3x - y + z) + (2x - y - z) - (3x - y - z) = 3x - y + z + 2x - y - z - 3x + y + z
Collect like terms: = 3x + 2x - 3x - y - y + y + z - z + z
Combine like terms: = 2x - y + z
Therefore, the coefficient of x is 2
Therefore, the coefficient of x is 2
6x^3 -24x^2 24x
3x^2 -12x 12
