3+4.5(2d-3)=7.5

3 + 4.5 (2 d - 3) = 7.5

d = 2

Solution steps

3 + 4.5 (2 d - 3) = 7.5

Multiply both sides by

10

30 + 45 (2 d - 3) = 75

Move

30

to the right side

45 (2 d - 3) = 45

Divide both sides by

45

2 d - 3 = 1

Move

3

to the right side

2 d = 4

Divide both sides by

2

d = 2

- 4 = s - 1

n, c = 12 n - 5

- 1.7 y + 1.6 = 3.98

0.5 (7 m - 5) + 4 = 8 (2 m + 0.5)

\frac{2}{3} y = 8
