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

The lines y = 10x − 6 and y = 164 meet at x = 17. 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.
$10x - 6 = 164$
2
Add 6 to both sides:
$10x - 6 + 6 = 164 + 6 \ \Rightarrow\ 10x = 170$
3
Divide both sides by 10:
$\frac{10x}{10} = \frac{170}{10} \ \Rightarrow\ x = 17$
4
Check: put x = 17 back into the equation.
$10\cdot17 - 6 = 170 - 6 = 164 \checkmark$
