i don't kow how to sole this equation 5x-10=2x-7 can u help me
5x-10-2x+7=0
3x-3=0
3x=3
x=1
5x-10=2x-7
Add 10 to both sides.
5x=2x+3
Subtract 2x from both sides.
3x=3
Divide both sides by 3.
x=1
This way is the more common method although Emily did get the correct answer.
I'm in 7th grade too but I studied this last year so:
5x-10=2x-7
-2x -2x
3x-10= -7
+10 +10 (because -10 and -7 are -)
3x = 3 Then divide out
x=1
Of course, I can help you solve the equation 5x-10=2x-7. Here's a step-by-step explanation of how to do it:
1. Start by simplifying both sides of the equation. Combine like terms on each side.
5x - 10 = 2x - 7
Subtract 2x from both sides:
3x - 10 = -7
2. Next, isolate the variable term on one side of the equation. To do this, add 10 to both sides of the equation.
3x - 10 + 10 = -7 + 10
Simplify:
3x = 3
3. Now, to solve for x, divide both sides of the equation by the coefficient of x (which is 3).
(3x)/3 = 3/3
Simplify:
x = 1
So, the solution to the equation 5x-10=2x-7 is x = 1.
