5x - 4x = 13 - 3 ie x = 10
5x-3 = 11+12x 5x-12x = 11+3 -7x = 14 x = -2
5x + 3 = 18 Subtract 3 from both sides: 5x = 15 Divide by 5: x = 3.
Then x = 6 Therefore; 5x + 3 = 33 First you have to solve the value of X: 8X + 5X + 2X +4X = 114; OR 19x = 114. When you divide both sides of the equation by 19 to solve for X, you find that X = 6. Ergo, 5X + 3 = 30 + 3 = 33; hence, 5X + 3 = 33.
x=-3
5x plus 3 does equal 3 plus 5x; commutative law.
3(x + 2) = 5x - 12 3x + 6 = 5x - 12 6 = 2x - 12 6 + 12 = 2x x = 9
33
12 = 3x, so x = 4
(x - 4)(2x + 3)
5x - 3 + x - 9 = 5x Bring like terms together of the left side: 5x + x - 3 - 9 = 5x Combine like terms: 6x - 12 = 5x Add 12 to both sides: 6x = 5x + 12 Subtract 5x from both sides: x = 12
5x+3 = -17 5x = -17-3 5x = -20 x = -4
X=-3
x2 + 4x - 9 = 5x + 3 ∴ x2 - x - 12 = 0 ∴ (x + 3)(x - 4) = 0 ∴ x ∈ {-3, 4}
5x - 4x = 13 - 3 ie x = 10
-.6x+.5x+9=-3 -.1x=-12 x=120
5x+3 = 3x+11 5x-3x = 11-3 2x = 8 x = 4
