Answer:
To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.

Answer:
Step-by-step explanation:
First you would find 3y to the 2 power which would have a product of 9y. The little carrot looking symbole represents a power which in this case the power is 2. You are not multiplying 3 by 2 you are multiplying 3 two times which would give you a product of 9. Than you would subtract 3y from 9y which would give you a product of 6y. You would subtract these two numbers because they are like factors which means they have the same variable which in this case is y. Finally you would be left with 6y-90 and that would give you your answer, because 6y and 90 are not like factors therefore you can not subtract 6y from 90
There is one solution.
Just divide the 2nd line by two to get -2x + y= 3, then put it in slope-intercept to get y= -2x + 3
THen
y=2x+3
y= -2x + 3 subtract
4x=0
so x=0
plug in 0 for x
y= 2(0) +3
so y =3.
plug in to check
3=0+3 checkmark
-4(0) +2(3) = 6 checkmark
