Solve 1(x+7)=3.5

$$1 ( x + 7 ) = 3.5$$

Solve for x

$$x=-3.5$$

Steps for Solving Linear Equation

Divide both sides by 1.

$$x+7=\frac{3.5}{1}$$

Expand \frac{3.5}{1} by multiplying both numerator and the denominator by 10.

$$x+7=\frac{35}{10}$$

Reduce the fraction \frac{35}{10} to lowest terms by extracting and canceling out 5.

$$x+7=\frac{7}{2}$$

Subtract 7 from both sides.

$$x=\frac{7}{2}-7$$

Convert 7 to fraction \frac{14}{2}.

$$x=\frac{7}{2}-\frac{14}{2}$$

Since \frac{7}{2} and \frac{14}{2} have the same denominator, subtract them by subtracting their numerators.

$$x=\frac{7-14}{2}$$

Subtract 14 from 7 to get -7.

$$x=-\frac{7}{2}$$
