-2x + 3y = -7
3x + y = 16
simultaneous equations.
Elimination a letter. Arbitrarily select 'y'
Hence multiply the bottom eq'n by ' -3'
Hence
-2x + 3y = -7
-9x - 3y = -48
Add the eq'ns/
-11x = =55
x = -55/-11 = 5
When x = 5 , substitute into either eq'n for 'y'
-2(5) + 3y = -7
-10 + 3y = -7
3y = 3
y = 1
Hence answer in ( x,y) fpr, is ( 5,1).

3x
What is -3x plus -18 equals 2x plus 7?
-3x + (-18) = 2x + 7 +18 +18 -3x = 2x +25 -2x -2x -5x = 25 ----- ----- -5 -5 x=-5 *------- equals a division line
3x - 9 equals -2x plus 16?
x = 5 ========== 3x - 9 = -2x + 16 Balance the equation by adding 2x and 9 to both sides: 3x + 2x = 16 + 9 5x = 25 Divide both sides by 5 to get value for x: x = 5
