Question

2x-3=7
what is the expression for this equation ​

Answer 1

x is equal to 5

Step-by-step explanation:

• For this problem, we need to add the coefficient; 3, to both sides of this equation.

`2x-3+3=7+3`

• 2(x) - 3 + 3 = 7 + 3
• The problem is not knowing what x is just yet. However, we can simplify at least knowing 7 + 3 is ten.

`2x=10`

• Now, we must divide both sides by 2, since it is the leading term in this equation. However, x cannot be divided by anything yet because x has a value likely to be more than one. That's why we exclude x from this division.

`(2x)/(2)=(10)/(2)`

• Why 2x ÷ 2 could only be 10: 10 is the coefficient meaning it stands by itself while 2 is what we're dividing it by. 2 came from the canceled variable(x) while 10 was from simplification. Divide 10 by 2.

`(10)/(2) = 5`

• Therefore, x is five.
