3 + 5 = 4*b so 8 = 4*b Divide both sides by 4: 2 = b
12x = 4(x+5) 3x = x+5 divide by 4 2x = 5 subtract x x = 2.5 divide by 2
Evaluate -4(a+b) - 10a/b when a=8 and b=5
So your problem is: 4x=5+5+5+5 OK, so u add all the 5's up: 4x=20 Then you divide 4 by 20: 4/20= 5 Therefore x= 5
the answer to that is 5

3 + 5 = 4*b so 8 = 4*b Divide both sides by 4: 2 = b
12x = 4(x+5) 3x = x+5 divide by 4 2x = 5 subtract x x = 2.5 divide by 2
Evaluate -4(a+b) - 10a/b when a=8 and b=5
-3y+5=-4 subtract 5 from each side of the equation: -3y=-9 Divide by -3 to get the variable alone:y=3
7+2+5= 14 35 42
So your problem is: 4x=5+5+5+5 OK, so u add all the 5's up: 4x=20 Then you divide 4 by 20: 4/20= 5 Therefore x= 5
the answer to that is 5
true
4
5 + 3y = -4 First subtract 5 from both sides. 3y = -9 Then divide both sides by 3. y = -3
