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

The lines y = 10x + 6 and y = -94 meet at x = -10. 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 addition, then the multiplication.
$10x + 6 = -94$
2
Subtract 6 from both sides:
$10x + 6 - 6 = -94 - 6 \ \Rightarrow\ 10x = -100$
3
Divide both sides by 10:
$\frac{10x}{10} = \frac{-100}{10} \ \Rightarrow\ x = -10$
4
Check: put x = -10 back into the equation.
$10\cdot(-10) + 6 = -100 + 6 = -94 \checkmark$
