Solve -1=-2/7(6)+b

$$- 1 = - \frac { 2 } { 7 } ( 6 ) + b$$

Solve for b

$$b=\frac{5}{7}\approx 0.714285714$$

Steps for Solving Linear Equation

Express -\frac{2}{7}\times 6 as a single fraction.

$$-1=\frac{-2\times 6}{7}+b$$

Multiply -2 and 6 to get -12.

$$-1=\frac{-12}{7}+b$$

Fraction \frac{-12}{7} can be rewritten as -\frac{12}{7} by extracting the negative sign.

$$-1=-\frac{12}{7}+b$$

Swap sides so that all variable terms are on the left hand side.

$$-\frac{12}{7}+b=-1$$

Add \frac{12}{7} to both sides.

$$b=-1+\frac{12}{7}$$

Convert -1 to fraction -\frac{7}{7}.

$$b=-\frac{7}{7}+\frac{12}{7}$$

Since -\frac{7}{7} and \frac{12}{7} have the same denominator, add them by adding their numerators.

$$b=\frac{-7+12}{7}$$

Add -7 and 12 to get 5.

$$b=\frac{5}{7}$$
