7x + 2 = -4 7x + 2 - 2 = -4 - 2 7x = -6 7x/7 = -6/7 x = -6/7
Assume you mean -7x-2=0 solve for x -7x-2=0 -7x=2 -x=2/7 X=-2/7
Step 1. 7 = 7x +2 Step 2. subtract 2 from both sides: 7 - 2 = 7x + 2 - 2 and simplify: 5 = 7x Step 3. divide both sides by 7: (5/7) = (7x/7) and simplify 5/7 = x x = 5/7 or about 0.714285
4x2 + 28x + 49 = 4x2 + 14x + 14x + 49 = 2x(2x + 7) + 7(2x + 7) = (2x + 7)(2x + 7) or (2x + 7)2
7x + 2 = 3Subtract 2 from both sides:7x = 1Divide both sides by 7:x = 1/7 or about 0.143
[ x3 - 4x2 + 7x ] / (x) = x2 - 4x + 7
7x / 2 = 3 7x=2(3) 7x=6 x=6/7 The answer is x=6/7
none of the above
-7
7x + 2 = -4 7x + 2 - 2 = -4 - 2 7x = -6 7x/7 = -6/7 x = -6/7
Assume you mean -7x-2=0 solve for x -7x-2=0 -7x=2 -x=2/7 X=-2/7
Step 1. 7 = 7x +2 Step 2. subtract 2 from both sides: 7 - 2 = 7x + 2 - 2 and simplify: 5 = 7x Step 3. divide both sides by 7: (5/7) = (7x/7) and simplify 5/7 = x x = 5/7 or about 0.714285
Given 3x3 + 4x2 +x + 7 is divided by x2 + 1, find the results:
Two step equations are really simple these are the steps... EX. 7x+2=23 do the opposite operation so u subtract 2 from both sides 7x=21 now since 7x is multiplying , you do the opposite and you divide both sides 7x/7=21/7 the 7 from 7x and the seven you divided by cancel out each other so now you only have x on the other side 21 divided by 7= 3 so the answer is x=3
-8x+7 = -7x-2 -8x = -7x-2-7 -8x=-7x-9 -8x+7x=-9 -1x=-9 x=-9/-1 x=9
Assume you mean -7x-2=0 solve for x -7x-2=0 -7x=2 -x=2/7 X=-2/7
7/x^6 = 7x^-6
