ax - b = c Add 'b' to both sides ax = c + b Divide both sides by 'a' x = (c + b) / a The answer!!!!!
A linear equation.
Taking it step by step: 2b - b - 10 = -13 b - 10 = -13 b = -13 + 10 b = - 3
A = coefficient matrix (n x n) B = constant matrix (n x 1)
it's the bit in the square root sqrt of (b squared minus 4ac) when a,b and c are the values belonging to the equation ax(sqared) plus bx plus c
If a,b, and c are positive a < x < b means ax < cx If a,b , and c are negative a < x < b means ax > cx
x = (d-a)/(a-c)
ax - b = c Add 'b' to both sides ax = c + b Divide both sides by 'a' x = (c + b) / a The answer!!!!!
If a equals 3 and b equals minus 5 then a minus b equals what
Ax + B = Bx + C Ax - Bx = (C - B) x (A - B) = (C - B) x = (C - B) / (A - B)
ax - b = c ax = b + c x = (b + c)/a
ax + b = 15 or ax + b = -15
13
a - b = c -(a - b) = -c b - a = -c
It is a straight line with gradient -A/B and intercept C/B.
The most general form is (ax - b)*(cx - d) = k where a, b, c, d and k are constants.
2x - 13x + 42 = x +ax + b a + b = 2(x - 6.5x + 21) = 34 = a + b
