Set up equation:
What number plus
637
637
637
, when multiplied by
223
223
223
, equals
773
773
773
multiplied by
223
223
223
plus
637
637
637
multiplied by
223
223
223
?
Simplify right side:
Simplify the right side of the equation:
773
⋅
223
+
637
⋅
223
773 \cdot 223 + 637 \cdot 223
773
⋅
223
+
637
⋅
223
.
Factor out common term:
Factor out the common term
223
223
223
from the right side:
(
773
+
637
)
⋅
223
(773 + 637) \cdot 223
(
773
+
637
)
⋅
223
.
Calculate sum:
Calculate the sum inside the parentheses:
773
+
637
=
1410
773 + 637 = 1410
773
+
637
=
1410
.
Divide by
223
223
223
:
Now the equation looks like:
(
x
+
637
)
⋅
223
=
1410
⋅
223
(x + 637) \cdot 223 = 1410 \cdot 223
(
x
+
637
)
⋅
223
=
1410
⋅
223
.
Subtract
637
637
637
:
Since both sides are multiplied by
223
223
223
, we can divide both sides by
223
223
223
to simplify:
x
+
637
=
1410
x + 637 = 1410
x
+
637
=
1410
.
Calculate x:
Solve for x by subtracting
637
637
637
from both sides:
x
=
1410
−
637
x = 1410 - 637
x
=
1410
−
637
.
Calculate x:
Solve for x by subtracting
637
637
637
from both sides:
x
=
1410
−
637
x = 1410 - 637
x
=
1410
−
637
. Calculate x:
1410
−
637
=
773
1410 - 637 = 773
1410
−
637
=
773
.
