For instance you have -2(x+7) if you were to rename the problem without parentheses it would be -2•x+7. You multiplied the x+7 in the parentheses by -2 that's outside the parentheses

The point (3, 2) is the solution to given system of equations
<em><u>Solution:</u></em>
Given that system of equations are:
------ eqn 1
------- eqn 2
From eqn 2,
y = 2x - 4
Substitute y = 2x - 4 in eqn 1
Let us solve the above equation by quadratic formula,
Using the Quadratic Formula for 
where a = 5, b = -16, and c = 3
The discriminant 
so, there are two real roots.
Substitute for x = 0.2 and x = 3 in 2x - y = 4
<em><u>when x = 3</u></em>
2(3) - y = 4
6 - y = 4
y = 2
<em><u>when x = 0.2</u></em>
2(0.2) - y = 4
0.4 - y = 4
y = 0.4 - 4
y = -3.6
Thus Option D is correct The point is (3, 2)
First, take out the whole number portion, and solve the decimal part, which is 0.85. 0.85 = 85/100. So, the mixed number would be 2 85/100. However, most teachers want you to simplify your mixed numbers, so divide both numbers by a factor that you think is common. 5 is a common factor, so 85/5 = 17. 100/5 = 20. So, the answer is simplified to 2 17/20.
