(8)=-1(5)+b

(8) = - 1 (5) + b

b = 13

Solution steps

(8) = - 1 \cdot (5) + b

Switch sides

- 1 \cdot (5) + b = (8)

Remove parentheses:

(a) = a

- 1 \cdot 5 + b = (8)

Multiply the numbers:

1 \cdot 5 = 5

- 5 + b = 8

Move

5

to the right side

b = 13

2 m^{2} - 7 m - 13 = - 10

\frac{25 x ^{7} y ^{8}}{5 x ^{5} y}

\frac{x ^{2}}{4} + 3 x = 49

7 x^{2} - 12 x + 5 = 0

8 x = 4 x^{2} - 1
