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

The lines y = 11x + 1 and y = -98 meet at x = -9. 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.
$11x + 1 = -98$
2
Subtract 1 from both sides:
$11x + 1 - 1 = -98 - 1 \ \Rightarrow\ 11x = -99$
3
Divide both sides by 11:
$\frac{11x}{11} = \frac{-99}{11} \ \Rightarrow\ x = -9$
4
Check: put x = -9 back into the equation.
$11\cdot(-9) + 1 = -99 + 1 = -98 \checkmark$
