For 2x - 3 = 10 you have to find the value of x. So, whatever times 2, minus 3 equals 10 is your answer, in this case x = 6.5, or 6 1/2.

2x - 3 = 10
2x - 3 + 3 = 10 +3
2x = 13
2x / 2 = 13/2
x = 13/2

x = 13/2
Explanation:
2x - 3 = 10 -------- Add 3 to both sides of the equation
2x - 3 + 3 = 10 + 3 --> 2x = 13 ------- Divide both sides by 2
2x/2 = 13/2 --> x = 13/2, which is equivalent to x = 6.5

2x - 3 = 10
2x - 3 +3 = 10 + 3, add 3 to both sides so x will be by itself
2x=13
2x/2 = 13/2, divide by 2
x = 6.5

2x - 3= 10
Add 3 to both sides to cancel -3
2x = 10+3
add
2x = 13
divide both sides by 2
x = 13/2
x = 6.5
