15+b = 23
Subtract 15 from both sides
b = 8
8 plus 15 = 23
(-15) + 23 = 8
23
15 + 41 + 23 = 79
It does not help you.
Can you help with this equation? Thanks. Solve for x and y and z for the following. x plus y plus z equals 9 x plus 2y plus 3z equals 23 x plus 5y plus -3z equals -7
-15 over 23
X = 12
By including its plus or minus signs
h + 23 = 32 Subtract 23 from both sides: h = 32 - 23 = 9
-4x+3 = 23+6x -4x-6x = 23-3 -10x = 20 x = -2
