2+2=2x+2
-2 to both sides
2=2x
Divide 2
X=1
Let's actually find the solution of
<span>2x - 6y = 8
-x + 3y = 10
Let's use the addition/subtraction method. Multiply the 2nd equation by 2, obtaining
</span> 2x - 6y = 8
-2x + 6y = 20
--------------------
0 + 0 = 28
Since this can never be true, the system of linear equations
2x - 6y = 8
-x + 3y = 10
has no solution.
Answer:
$150
Step-by-step explanation:
You can do this by forming an equation.
30% = 0.30. Let the original price be x dollars. Then:-
x - 0.30x = 105
0.70x = 105
x = 105/0.70
x = $150
Answer:
7 cm
Step-by-step explanation:
The two triangles are similar, so you can set up a proportion where (36/6) = (42/x). When you solve for x, you get seven.
