5= 1/2 (7x+4)

5 = \frac{1}{2} (7 x + 4)

x = \frac{6}{7}

Decimal Notation

x = 0.85714 \dots

Solution steps

5 = \frac{1}{2} (7 x + 4)

Switch sides

\frac{1}{2} (7 x + 4) = 5

Multiply both sides by

2

7 x + 4 = 10

Move

4

to the right side

7 x = 6

Divide both sides by

7

x = \frac{6}{7}

(x + 1)^{2} - (x - 1)^{2} + 12 \geq 0

9 x^{2} - y^{2}

∣ 2 - 3 x ∣ = 4

lo g_{9} (\frac{1}{81})

2 x^{2} - 13 x + 20 = 0
