Explain it step by step in chat Make a short video of it

The lines y = 10x − 14 and y = 146 meet at x = 16. The solution of the equation is the x-coordinate of the point where the two sides are equal.

How to work it out

1
The goal is to get x alone. Undo the operations in the opposite order: first the subtraction, then the multiplication.
$10x - 14 = 146$
2
Add 14 to both sides:
$10x - 14 + 14 = 146 + 14 \ \Rightarrow\ 10x = 160$
3
Divide both sides by 10:
$\frac{10x}{10} = \frac{160}{10} \ \Rightarrow\ x = 16$
4
Check: put x = 16 back into the equation.
$10\cdot16 - 14 = 160 - 14 = 146 \checkmark$
