Solve each equation. Check your solution.

x+3=2

Short Answer

Expert verified

The solution of given equation is x=-1.

Step by step solution

01

– Subtraction property of equality.

According to the subtraction property of equality, if a=b, then a-c=b-c, where a,b,c are real values.

02

– Given information.

The given equation is:

x+3=2

03

– Solve the given equation.

The given equation is:

x+3=2

Subtract 3from both sides of the above equation.

x+3鈭�3=2鈭�3x=鈭�1

Thus, the solution of given equation is x=-1.

04

– Verify the solution.

If left hand side of the given equation is equal to the right hand side of the equation for x=-1then it is the correct solution.

Substitute x=-1in the given equation.

鈭�1+3=22=2

Left hand side is equal to the right hand side. Thus the solution x=-1 is correct.
