What is the sum of 1.57 and 6.88?
Ok, so lets work this out together!
Sum means add.
6.88
+ 1.57
That would be:
= 8.45
Hope i helped!
14-4x=2y
divide both sides by 2
7-2x=y
subsitute 7-2x for y
7-2x+2x=7
add like terms
7=7
true
therefor these 2 equations are the same and there are an infinite number of equations
answer is C
Answer:What number must be multiplied by 3 to obtain 15? ... Example 11 A student solved the equation 5x - 3 = 4x + 2 and found an answer of x = 6. ... Example 12 3x = 6 and 2x + 1 = 5 are equivalent because in both cases x = 2 is a solution. ... + 3x = 7x + 2 - 4x can be changed to a simple equation x = 3, and the equation x = 3 is .
