53 - 2 d = 56 d - d + 3

d = \frac{50}{57}

Decimal

d = 0.87719 \dots

Solution steps

53 - 2 d = 56 d - d + 3

Add similar elements:

56 d - d = 55 d

53 - 2 d = 55 d + 3

Move

53

to the right side

- 2 d = 55 d - 50

Move

55 d

to the left side

- 57 d = - 50

Divide both sides by

- 57

d = \frac{50}{57}

3 x + 3 = 90

(x + 3)^{2} - (x + 1) (x - 2) = 3 x

3 (3) + 4 = 5 y - 2

x - 7 = - 13

x - 7 = - 7
