You said that 42x - 3 + 7 = 8x + 5 .
Combine the like terms on the left side (the -3 and the +7):
42x + 4 = 8x + 5
Subtract 4 from each side:
42x = 8x + 1
Subtract 8x from each side:
34x = 1
Divide each side by 34:
x = 1/34
The solution set is: {34}
3 plus 3 plus 3 plus 3 plus 3 plus 3 plus 3 plus 3 plus 3 plus 3 plus 3 plus 3 plus 3 plus 3 plus 3 plus 3 plus 3 plus 3 is 54.
29.......just add
3plus 3 times 3plus 3
A solvent plus a solute equals a solution.
70000000y=35t
to find a solution, you need to also have what x+2 equals.
y = 5

What is the number of integral solution to x plus y plus z equals 100?
Al and AgNO3. Al has a 3plus charge plus 3e negative. 3(Ag positive plus le negative equals Ag). Al plus 3Ag plus is equal to Al with a 3 plus charge plus 3Ag.
The answer is (3.5)2 plus (4)2 equals 410.
The solution is (x, y, z) = (2.5, 1, 2.5).
