Answer 5

x2−3=x7+2

Add 2 to 7 to get 9.

x2−3=19x

Subtract 3 from 2 to get −1.

x−1=19x

Move the minus sign from the denominator to the front of the expression.

−11x=19x

Any expression divided by 1 is the expression.

−x=19x

Since x9 contains the variable to solve for, move it to the left-hand side of the equation by subtracting x9 from both sides.

−x−19x=0

To add fractions, the denominators must be equal. The denominators can be made equal by finding the least common denominator (LCD). In this case, the LCD is 9. Next, multiply each fraction by a factor of 1 that will create the LCD in each of the fractions.

−19x−x⋅99=0

Complete the multiplication to produce a denominator of 9 in each expression.

−19x−9x9=0

Combine the numerators of all expressions that have common denominators.

19(−x−9x)=0

Since −x and −9x are like terms, subtract 9x from −x to get −10x.

−10x9=0

Move the minus sign from the numerator to the front of the expression.

−10x9=0

Multiply both sides of the equation by 9.

−10x=0⋅(9)

Any expression with a factor of 0 in the numerator is equal to 0.

−10x=0

Divide each term in the equation by −10.

−10x−10=0−10

Simplify the left-hand side of the equation by canceling the common factors.


x=0−10

Simplify the equation.

x=0
