x=6
7x + 4 = 2x + 5Subtract 4 from each side of the equation:7x = 2x + 1Subtract 2x from each side:5x = 1Divide each side by 5:x = 1/5 = 0.2
5x - 3y -7x + 2y +3x = (5-7+3)x + (-3+2)y = x - y
-5x + 13 = -12 -5x = -12 - 13 = -25 x = -25/-5 = 5
5x+10=40 5x+10-10=40-10 5x=30 5x/5=30/5 x=6
x=6
2x + 5x = 357x = 35x = 35/7x = 5
7x + 12 = 5x + 2 Subtract '12' from both sides Hence 7x = 5x -10 Subtract '5x' from both sides. 2x = -10 Divide both sides by '2' Hence x = -5 .
7X-1=9+5X. add 1 to both sides 7X=10+5X. Subtract 5X and get 2X=10 divide by 2 and x=5
5x2+7x = 12 5x2+7x-12 = 0 (5x+12)(x-1) = 0 x = -12/5 or x = 1
2x + 5x = 35 7x = 35 x = 35/7 x = 5
7x-1=2x+5 7x-2x=5+1 5x=6 x=6/5=1.2
Double first equation: 10x + 2y = 10Subtract second equation: 7x = 7x = 1, y = 0
If you mean 5x^2 -7x +2 = 0 then it is a quadratic equation with solutions of x = 2/5 or x = 1
2x + 5x = 35 7x = 35 divide each side by 7 x = 5
Like terms are: 5x -7x +2x and 3 -5
65 = 2x - 7x 65 = -5x 65/-5 = -5x/-5 -13 = x
