3x + 7 = x
First, subtract 3x from both sides. / Your problem should look like: 7 = x - 3x
Second, simplify x - 3x to -2x. / Your problem should look like: 7 = -2x
Third, divide both sides by -2. / Your problem should look like:

= x
Fourth, simplify

to

/ Your problem should look like:

= x
Fifth, switch sides. / Your problem should look like: x =

Answer as fraction:

Answer as decimal: -3.5
Answer: Fourth option:
Triangle ZYB is congruent with triangle OWR, by SSS
SSS: Side Side Side, because the three sides are given, and they are congruent
we are given
x-intercept is 3
so,
a=3
y-intercept is 2
b=2
now, we can intercept formula of line

now, we can plug
a=3 and b=2

now, we will get rid of denominators
so, we can multiply both sides by 6


we can also write it as

so, option-D..................Answer
11 is the only prime number. It's only multiples are 1 and itself
