Question

What is the value of x in the y = 2/3x + 5 when y=7?

Answer 1

Answer:

x = 3

Step-by-step explanation:

y = 2/3 x + 5; y = 7

7 = (2/3)x + 5

2 = (2/3)x

x = 2 * 3/2

x = 3

Answer 2

Answer:

x=3

Step-by-step explanation:

To start all you need to do is replace $y$ with 7 to get $7=\frac{2}{3}x+5$

Then, you need to isolate x on the right side of the equation, starting with subtracting 5 on both sides to get $2=\frac{2}{3}x$

Finally, you divide both sides by $\frac{2}{3}$. You divide fractions by multiplying the reciprocal like so $\frac{2}{1} *\frac{3}{2} =x$ to get $\frac{6}{2} =x$. This means that x=3
