4 + x = 2x Subtract 'x' from both sides 4 = 2x - x x = 4 Verification 4 + 4 = 2(4) 8 = 2 x 4 = 8 True!!!!!
2x - 1 = 3x + 4 Subtract 2x from both sides: - 1 = x + 4 Subtract 4 from both sides: -5 = x
Subtract x so -4 = 2x/ x= -2
3x + 4 = 2x - 3 Subtract 2x from both sides: x + 4 = - 3 Subtract 4 from both sides: x = -7
x=4From superscot85: How you solve it is to subtract 4 from each side leaving x = 4
Subtract it from WHAT!
4 + x = 2x Subtract 'x' from both sides 4 = 2x - x x = 4 Verification 4 + 4 = 2(4) 8 = 2 x 4 = 8 True!!!!!
it is 1000 taking away 200 4 times
2x - 1 = 3x + 4 Subtract 2x from both sides: - 1 = x + 4 Subtract 4 from both sides: -5 = x
Subtract x so -4 = 2x/ x= -2
3x + 4 = 2x - 3 Subtract 2x from both sides: x + 4 = - 3 Subtract 4 from both sides: x = -7
x + 4 = 2x subtract x to both sides; 4 = x, so 4 + 4 = 2(4) 4 + 4 = 8 true
-2
x + 3 = 2x + 4 Subtract x from both sides: 3 = x + 4 Subtract 4 from both sides: - 1 = x y = x + 3 = -1 + 3 = 2 The solution is (x, y) = (-1, 2)

Subtract the exponents. x^4 divided by x = x^3
