2x + 5x = 357x = 35x = 35/7x = 5

5x+4x-10 = 35 9x = 35+10 9x = 45 x = 5
3 + 5x = 38 -> 5x = 35 -> x = 7
=> 2x + 5x = 35{collect x's}=> 7x = 35{divide both sides by 7}=> x = 35/7 = 5
5x + 6 = 1 / 4(13x-11)(5x+6)(4)(13x-11)= 14(65x2-55x+78x-66)=1260x2 +92x-264-1=0260x2+92x-263=0Graph y = 260x2 +92x -263 and find its zero or use the quadratic formula
2x + 5x = 35 7x = 35 x = 35/7 x = 5
2x + 5x = 357x = 35x = 35/7x = 5

5x+4x-10 = 35 9x = 35+10 9x = 45 x = 5
3 + 5x = 38 -> 5x = 35 -> x = 7
2x + 5x = 357x = 35x = (35 / 7) = 5
x=35
=> 2x + 5x = 35{collect x's}=> 7x = 35{divide both sides by 7}=> x = 35/7 = 5
2x+3x=35 5x=35 x=7
2x + 5x = 35 7x = 35 divide each side by 7 x = 5
Start by subtracting 35 from both sides to get 5x = -65 Now, divide both sides by 5 to get x = -13
