In order to solve for a variable, you need to get it by itself on one side of an equation. Depending on the equation, there are different steps to do that.
Answer:
(2, - 2 )
Step-by-step explanation:
y = - 3 + 
x → (1)
3x + 2y = 2 → (2)
Substitute y = - 3 + x into (2)
3x + 2(- 3 + x) = 2 ← distribute parenthesis and simplify left side
3x - 6 + x = 2
4x - 6 = 2 ( add 6 to both sides )
4x = 8 ( divide both sides by 4 )
x = 2
Substitute x = 2 into (1)
y = - 3 + (2) = - 3 + 1 = - 2
solution is (2, - 2 )
Answer:
7
Step-by-step explanation:
You divide the number of visits and the price. 14÷2=7
There is no solution for this equation since they have the same slope, x/1. The only difference between these two is that their y intercepts are different meaning that they will be parallel lines that will never intersect among one other. For example, think of it as two separate lines that are have the same slope and never gain more distance/units from one another.
Solve:
To solve, you have to get one of this equations into a Ax+By=C equation form, standard equation. Let’s change y=x+4 into a standard equation.
We have to get x and y together and 4 as C.
So let’s subtract x from both sides;
y=x+4
-x -x
————————
-x+y=4
This is a standard equation.
Now let’s substitute.
take the standard equation and plug in y which is x+4 since there is a equation meaning it’s y=x+4
-x+(x+4)=4
Let’s simplify this mess.
-x+x equals 0. So we are left with 4=4.
Subtract 4 from both sides and we get 0=0
This means there is no solution. Hoped this helped.
6/7 is in fraction format . . . for it to be in decimal format it would be 0.8571 . . .
