They also consist of mathematical operations such as addition, subtraction, division, multiplication, etc
Given the expression;
-5x + 7y = 8x + 7
collect like terms
-5x - 8x + 7y = 7
add like terms
-13x + 7y =7
equate the equation to zero
- 13x + 7y - 7 = 0
Thus, the expression is simplified to - 13x + 7y - 7 = 0
