Question

What is two-thirds a number plus 4 is 7

Answer 1

$two-thirds: \frac{2}{3} \\ number: b \\ plus: + (add) \\ 4: 4 \\ is: equal (to) \\ 7:7 \\ \\ \\ \\ Problem: \frac{2b}{3} + 4 = 7$

Finding our answer (if we had to solve it as well)↓

$\frac{2}{3}b + 4 - 4 \\ 7 - 4 = 3$

$\frac{2}{3}b = 3$

$\frac{3}{2} ( \frac{2}{3})$ (← cancel this out because that would give you a $1$ by itself $\frac{3}{2} (3) = \frac{9}{2}$

$Answer: B = \frac{9}{2}$

Answer 2

2/3x + 4 = 7
         -4    -4
4 cancels out.
2/3x = 3
x 3      x3
6/3 = 2x = 9
         /2     /2
2 cancels out.
x = 9/2 = 4.5
