61=-3+(4-1)d

61 = - 3 + (4 - 1) d

d = \frac{64}{3}

Decimal Notation

d = 21.33333 \dots

Solution steps

61 = - 3 + (4 - 1) d

Switch sides

- 3 + (4 - 1) d = 61

Subtract the numbers:

4 - 1 = 3

- 3 + 3 d = 61

Move

3

to the right side

3 d = 64

Divide both sides by

3

d = \frac{64}{3}

5 x - 1 = 2 x - 7

\frac{3}{4} (8 x - 4) = 12

- 28 + 7 x = 3 (3 x - 6)

3 \cdot (- y) = 2

y - 6.72 = 2.53
