For this case, the first thing we must do is define a variable.
We have then:
x: unknown number.
We then have the following equation:
\(2x + 10 = 40
\)
To clear the value of x we follow the following steps:
Step 1:
Pass the value of 10 subtracting:
\(2x = 40 - 10
2x = 30
\)
Step 2:
Pass the value of 2 dividing:
\(x = \frac{30}{2}
x = 15
\)
Answer:
a 2 step equation that equals 15 is:
\(2x + 10 = 40\)
