Answer:
Explanation:
Start by solving for x. It can be done mentally by subtracting 10x from both sides of the equation. We will then take the absolute value, so that if our answer turns out to be negative, it does not affect the final outcome.
Left-hand side (-2) equals -4 Left-hand side (10x) minus 10x = 0 Right hand side (2x)=6 Absolute Value +both sides=6 After this first step we therefore know that x is equal to 6. From here, use parentheses to arrange each equation separately and find what numbers need to be multiplied or subtracted in order for them to align with the other equation correctly. Units do not matter as they will cancel
