5a-10(3)=45

5 a - 10 (3) = 45

a = 15

Solution steps

5 a - 10 (3) = 45

Remove parentheses:

(a) = a

5 a - 10 \cdot 3 = 45

Multiply the numbers:

10 \cdot 3 = 30

5 a - 30 = 45

Move

30

to the right side

5 a = 75

Divide both sides by

5

a = 15

m^{2} - 16 = m^{2} + 6 m + 12

lo g_{15} (3.5) = 3 x

- 4 x - 7 = - 19

5 + \frac{1}{2} (14 b - 8) = - 6

\frac{2}{3} x - \frac{1}{2} = \frac{x + 3}{6}
