3x-7=5x+13, what is x?
3x-7=5x+13
3x - 5x = 13 + 7
-2x = 20
x = -?
x=-10 i think right cause u divide both sides by -2 and -2x over 2 cancel out and your left with 20 divided by -2 so its -10 !?!
To find the value of x, we need to isolate it on one side of the equation. Let's solve step by step:
Step 1: Simplify both sides of the equation by combining like terms.
Combine the "x" terms on the right side:
3x - 7 = 5x + 13
Subtract 3x from both sides:
-7 = 2x + 13
Step 2: Move the constant term to the other side of the equation.
Subtract 13 from both sides:
-7 - 13 = 2x
Simplify:
-20 = 2x
Step 3: Divide both sides by 2 to isolate x.
Divide by 2:
-20/2 = x
Simplify:
-10 = x
Therefore, the value of x is -10.
