4x-x-7x just combine all like terms 4x-x=3x rewrite 3x-7x= -4x. 4x-x-7x=-4x
Hope this helps have a nice day

Answer:
15
Step-by-step explanation:
Answer:
y=3x+10
Step-by-step explanation:
slope-intercept form: y=mx+b
You want to isolate the y so moving the -3x (slope) to the other side
y=3x+10
Step-by-step explanation:
27x² = 3*3*3*x*x
45x³y² = 3*3*5*x*x*x*y*y
Now
GCF = 3 * 3 *x * x = 9x²
