Answer:
If two expressions are equal to each other, and you add the same value to both sides of the equation, the equation will remain equal. When you solve an equation, you find the value of the variable that makes the equation true. In order to solve the equation, you isolate the variable
Step-by-step explanation:
The answer is 12 because u have to replace it -2(3)2(-1) and -2*3=-6 and 2(-1)=-2 and -6*-2=12
Answer:
b
Line y = −2x + 3 intersects the line y = −x + 1.
Step-by-step explanation:
We are given the following system of linear equations:
y = −2x + 3
y = −x + 1
Solution of a system of linear equations:
The solution of a system of linear equations is the point in which the two lines intersect.
In this question, the two lines are y = -2x + 3 and y = -x + 1, which means that the correct answer is given by option b.
Answer:
2x-37
Step-by-step explanation:
The first thing that you do when simplifying an expression with the variable’s values known is to distribute the values. EXAMPLE:
3(7x+9)+6(-16x-40); distribute:
21x+27-96x-240; combine like terms:
(21x+(-96x))+(27+(-240))——-> -75x-213; now plug in the values and solve: -75(6)-213=-663
