<span>3x-9x+6=20-3x+4x
Combine like terms.
-6x+6=20+x
Bring x over to the left side.
-x -x
-7x+6=20
bring 6 to the right side.
-6 -6
-7x=14
Divide -7 on both sides to isolate x.
x= -2

Answer:
2/3
Step-by-step explanation:
The ratio of any corresponding coordinates will give the scale factor.
Using the x-coordinates of C' and C, we have ...
scale factor = C'/C = 4/6 = 2/3
The dilation scale factor is 2/3.
Answer:
<em>It has infinitely as many solutions</em>
Step-by-step explanation:
Equations and Identities
When dealing with equations, we must find values of the variable who mak the expression become an identity.
The expression is an identity regardless on what the value of x is, so we can say the equation has infinite as many solutions. For example x=0 will make the expression look like 3=3 which is an identity. If x=8, we'll obtain 27=27 and so on
Step-by-step explanation:
4x - 2y = 8
y = -2
4x -2(-2) = 8
4x + 4 = 8
4x = 4
x = 1
