-5x-2.34=5.9
i got x=-1.648 is that correct
what is -13=10-x/2
i don't understand how do you solve this?
You are correct with -1.648
-13 = 10 - x/2
Subtract 10 from both sides
-23 = -x/2
Multiply both sides by -2 to solve for x.
so x=-46
It will be a +46 since -2 times -23 =+46
To solve the equation -5x - 2.34 = 5.9, follow these steps:
Step 1: Isolate the variable by moving the constant term to the other side of the equation.
-5x = 5.9 + 2.34
Step 2: Simplify the right side of the equation.
-5x = 8.24
Step 3: Divide both sides of the equation by the coefficient of x to solve for x.
x = 8.24 / -5
x = -1.648
Therefore, your answer of x = -1.648 is correct.
Now, let's solve the equation -13 = 10 - x/2.
Step 1: Begin by isolating the x term.
-13 + x/2 = 10
Step 2: Subtract 10 from both sides of the equation.
x/2 - 13 = 10 - 10
x/2 - 13 = 0
Step 3: Add 13 to both sides of the equation.
x/2 = 13
Step 4: Multiply both sides of the equation by 2 to solve for x.
2 * (x/2) = 13 * 2
x = 26
Therefore, the solution to the equation -13 = 10 - x/2 is x = 26.
