Just substitute any number for one variable to find the value of the other.
Eg:
2x-y=11
2(1)-y=11
2-y=11
-2 -2
-y=9
-y/-1=9/-1
y=-9
So (1,-9) is a solution to the equation.
Follow the steps and find many more solutions.
Hope I help you.

|j|=|2j+3| please help me
Softa [21]
Simplifying
j = (2j + 3)

Reorder the terms:
j = (3 + 2j)

Remove parenthesis around (3 + 2j)
j = 3 + 2j

Solving
j = 3 + 2j

Solving for variable 'j'.

Move all terms containing j to the left, all other terms to the right.

Add '-2j' to each side of the equation.
j + -2j = 3 + 2j + -2j

Combine like terms: j + -2j = -1j
-1j = 3 + 2j + -2j

Combine like terms: 2j + -2j = 0
-1j = 3 + 0
-1j = 3

Divide each side by '-1'.
j = -3

Simplifying
j = -3
