Answer:
2x+|y| = 11/14
Step-by-step explanation:
First, substitute variables.
2(-1/4) + |-9/7|
Change the whole number into a fraction for easier multiplication. The absolute value around -9/7 removes the negative, so it becomes positive 9/7.
= (2/1 * -1/4) + 9/7
= -2/4 + 9/7
= -1/2 + 9/7
Next, find a common denominator to add fractions. When you multiply fractions, multiply numerators with each other and denominators with each other.
(-1/2 * 7/7) + (9/7 * 2/2)
= -7/14 + 18/14
When you add fractions with a common denominator, keep the same denominator and add numerators.
-7/14 + 18/14 = 11/14
