Solve for X:
To solve the equation , we will isolate using division:
After performing the division, we get:
Thus, the solution to the equation is .
5
Solve for X:
\( x - 3 + 5 = 8 - 2 \)
You need to isolate x by getting it alone on one side. Since 5 is multiplied by x, you divide both sides by 5 to 'undo' the multiplication and keep the equation balanced.
You still divide both sides by the coefficient! Divide both sides by -5 to get x = -5. The negative sign stays with the coefficient.
No! When x has a coefficient (number multiplied by x), you must divide. Addition and subtraction are used when numbers are added or subtracted from x, like x + 3 = 8.
Substitute your answer back into the original equation. Replace x with 5: does 5(5) equal 25? Yes! So x = 5 is correct.
That's completely normal! Many equations have fractional or decimal solutions. Just make sure to substitute your exact answer back to verify it works.
