I’m not the best at math, but ⬇️
For example, apply the distributive property to the expression 3(2 + x) to produce the equivalent expression 6 + 3x; apply the distributive property to the expression 24x + 18y to produce the equivalent expression 6 (4x + 3y); apply properties of operations to y + y + y to produce the equivalent expression 3y
Step-by-step explanation:
y= 1
when x=2
here
when x= 3
y=4
