Write Equation:
First, let's write down the equation:
5
×
?
+
1
=
2
×
?
+
7
5\times ?+1=2\times ?+7

Terms Together:
Now, we need to get all the
x
x
x
terms on one side of the equation. So, we'll subtract
2
×
x
2\times x
2
×
x
from both sides:
5
×
x
−
2
×
x
=
2

−

x
=

Simplify:
After simplifying, we get
3
×
?
=
7
−
1
3\times ?=7-1
3
×
?
=
7
−
1
.
Subtract to Find Value:
Next, we subtract
1
1
1
from
7
7
7
to find the value on the right side of the equation:
3
×
?
=
6
3\times ?=6
3
×
?
=
6
.
Divide to Solve:
Now, we divide both sides by
3
3
3
to solve for
x
x
x
:
x
=
6
÷
3
x=6\div3
x
=
6
÷
3
.
Calculate Value:
Finally, we calculate
6
÷
3
6\div3
6
÷
3
to get the value of
?
?
?
:
?
=
2
?=2
?
=
