630 - x + 210 = 500 840 - x = 500 Now, subtract 840 from both sides: 840 - 840 - x = 500 - 840 -x = - 340
Now, divide by -1: x = 340
Second equation:
(x + 190) - 370 = 330
Simplify the equation: x + 190 - 370 = 330 x - 180 = 330
Now, add 180 to both sides: x - 180 + 180 = 330 + 180 x = 510
So, the solution to the system of equations is x = 340 and x = 510, which is not possible. It seems there may have been a mistake in one of the original equations.
First equation:
(630-x) +210 = 500
Simplify the equation:
630 - x + 210 = 500
840 - x = 500
Now, subtract 840 from both sides:
840 - 840 - x = 500 - 840
-x = - 340
Now, divide by -1:
x = 340
Second equation:
(x + 190) - 370 = 330
Simplify the equation:
x + 190 - 370 = 330
x - 180 = 330
Now, add 180 to both sides:
x - 180 + 180 = 330 + 180
x = 510
So, the solution to the system of equations is x = 340 and x = 510, which is not possible. It seems there may have been a mistake in one of the original equations.
