Hopes this helps:
Answer: x = -10/7
1. Simplify 2 • 2 to 4
4 + 7x + 6 = 0
2. Simplify 4 + 7x + 6 to 7x + 10.
7x + 10 = 0
3. Subtract 10 from both sides.
7x = -10
4. Divide both sides by 7.
X = -10/7
No solution
4(x-2+y) = 4(x-2+y)
4 × x = 4x
4 × -2 = -8
4 × Y = 4y
(for both problems)
4x-8+4y = 4x-8+y
-4x -4x
——————————
-8+4y = -8+4y
-8 -8
——————————-
4y = 4y
-4y -4y
————-
0=0
The answer to this equation is: x=5.5
Actually, one hundrerd 4 tens and 14 tens do NOT represent the same amount.
14 = 1 ten plus 4 ones.
