- 7 ∣ 10 + 3 m ∣ - 7 = - 63

m = - 6 or m = - \frac{2}{3}

Decimal Notation

m = - 6, m = - 0.66666 \dots

Solution steps

- 7 ∣ 10 + 3 m ∣ - 7 = - 63

Move

7

to the right side

- 7 ∣ 10 + 3 m ∣ = - 56

Divide both sides by

- 7

∣ 10 + 3 m ∣ = 8

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

10 + 3 m = - 8 or 10 + 3 m = 8

10 + 3 m = - 8 or 10 + 3 m = 8

m = - 6 or m = - \frac{2}{3}

∣ - 7 x ∣ = 28

∣ t + 5 ∣ = 8

∣ 4 - 2 x ∣ + 5 = 9

3 - 8 ∣ a + 6 ∣ = - 13

∣ t ∣ - 2 = - 1
